enfps can be two sides of distracted and focused

estjs can be two sides of withdrawn and outgoing
esfjs can be two sides of supportive and aggressive

estps can be two sides of relaxed and anxious
esfps can be two sides of down to earth (outspoken) and dreamy (softspoken)

enfjs can be two sides of sensitive and unbreakable

on the internet (and also otherwise), i've seen a lot of people typing characters as enfps because they're hyperactive and/or creative, and esfps because they're athletic and jumpy. this is not prescriptive, first of all, because as stated before, Ne is not based on creativity and Se is not based on physical action, even though there can be a tendency in behavior. but also, as stated before, behavior is not indicative of mbti. a character's psyche must be taken apart and analyzed to observe and determine mbti.

but on the generalization note between esfps and enfps...

esfps love having something to do. whether it's one thing or multiple things, and whether it requires interaction or physicality - it's never about that. it's about a) something to do, and b) something they like doing. esfps love having multiple ideas and options so they can find one to eventually settle on and work for. esfps are relatively good at maintaining not necessarily focus but at least a concentration of what needs to be done and actually doing it. they are good at getting into the work, and pretty much do it right away. they may have a variety of ideas, they may be enthusiastic about a lot of things; but essentially they are really good at sitting down and doing, as long as it's something they care about and like. their aux Fi is used as a support/drive so they can pick and choose what they like and don't like. they actually can be and really value creativity because that brings in a lot of possibilities to find something they do if they haven't settled on something yet. esfps are also prone to ambition (inferior Ni - an end goal in mind), performance anxiety (inferior Ni - worried about the results/plausibility of actions), and jumping into action to do things right away, sometimes well and sometimes too soon (dom Se/tert Te) but with that focus on doing. they are also prone to giving up because their inferior Ni might see the end goal as impossible or too far away.

e.g. gene from bob's burgers, manami from yowapeda, kagami from knb, hinata from haikyuu, dre from black-ish, ron from harry potter, finn from star wars, rin from love live, amethyst from steven universe, beast boy from teen titans (cartoon)

esfps immediately tackle and are good at what they do; that tends to be pretty distinctive of them. they really like new ideas and random shit and can be exuberant, intuitive, creative, and inspiring; but they also all have a similar vibe of wanting to do what they want to do. they need new ideas for this, more than anything.

enfps love new ideas. they're pretty much all over the place both abstractly and concretely. the healthier enfp has settled on one or a few things they like to do, but their ambition is more lighthearted than authentic focus (unless they're in the middle of working, in which case they are nothing but focus.) enfps bounce from possibility to possibility, because they naturally are aware that there are a lot of things they could like or enjoy; enfps are less naturally attuned to tasking than esfps are. enfps are prone to get an idea that they enjoy, idealize doing it, and then never do it. essentially they are really good at exploring a multitude of options even if they never do them, because they feel the need to always be mentally/abstractly/intellectually occupied even if they have nothing to show for it. enfps love new ideas because they are looking for something to do, and require tasks (more than working naturally) - they idealize working regularly, but they are cognitively full of so much that it takes some time for them to sit down and do. their aux Fi picks what they like from the possibilities and their tert Te likes to jump to it right away; they are also prone to giving up if their inferior Si isn't concentrated enough. if/when they do things right away, it's mostly because the idea is so strong to them that they want to see immediate results/their abstraction brought to life (dom Ne/tert Te), which can sometimes be done well or be too soon. their inferior Si is also what allows them to begin to focus on work as long as it pairs well with their aux Fi of what they personally like/enjoy.

e.g. linda from bob's burgers, gina from brooklyn nine nine, mabel from gravity falls, steven from steven universe, bokuto from haikyuu, junior from black-ish, seamus from harry potter, honoka from love live, starfire from teen titans (cartoon)

dominant function - what you do, your first method of interaction with the world
auxiliary function - what you thrive on, what fascinates you, what you should indulge and what needs to be indulged
tertiary function - what you use as support, subconsciously rely on without question or hesitance, often self-centered and conditional
inferior function - what you need to work on, a target end goal for your first three functions, what you can healthily understand and need in the most superficial ways, and also learn to take action on without letting the dominant function overwhelm it

so...
intp - initially approaches the world through perceived logic with self-contained independence, thrives on new ideas to fulfill or expand the logic, easily works in structure and focus/construction (simultaneous mental/physical) "if it matters", needs to and requires and eventually (if healthily) understands how people work/attention/acceptance (with relation to the dominant function: disregard logic in favor of the consideration of others)
intj - initially approaches the world through specific ideas deep inside their head, thrives on logical execution, easily references their emotions/justifies things to themselves through intrapersonal understanding "if it matters", needs to and requires and eventually (if healthily) interacts with the concrete world and take action (with relation to the dominant function: stop seeing things purely abstractly and internally and instead working with them with practicality & in the real world)
entp - initially approaches the world through a variety of ideas that they're fascinated by, thrives on reaching perceived logical conclusions, easily locates and discusses the emotions of other usually relative to themselves "if they matter" , needs and requires and eventually (if healthily) needs to consistently develop a structure and regular focus (with relation to the dominant function: don't be too caught up in fascination with external possibilities and learn to settle/construct)
infp - initially approaches the world through perceived self-judgment, thrives on new ideas to fulfill or expand the initial personal feelings, easily works in structure and focus/construction (simultaneous mental/physical) "if it matters", needs and requires and eventually (if healthily) needs to effectively carry out logical executions (with relation to the dominant function: instead of just emotionally reacting to everything)
infj - initially approaches the world through specific ideas deep inside their head, thrives on the importance and understanding the generalized emotive effect on others usually relative to themselves, easily works with logic and analysis through impersonal observation "if it matters", needs and requires and eventually (if healthily) interacts with the concrete world and take action (with relation to the dominant function: stop seeing things purely abstractly and internally and instead working with them with practicality & in the real world)
estj - initially approaches the world through logical execution, thrives on systematic method and focus, easily looks for/searches/accesses new ideas to fulfill the self, needs to and requires and eventually (if healthily) needs to self-reflect and understand and admit emotions and their intrapersonal relationship (with relation to the dominant function: to take time away from execution to fully see and understand the self in a rounded way and impact on others)
esfj - initially approaches the world in awareness of others/how people work and external interpersonality (even if not interactive or technically surrounded by others), thrives on systematic methods and focus (in order to help, or execute, but of course in general), easily accesses/searches for/new ideas to fulfill the self, needs to and requires and eventually (if healthily) needs to look at things analytically (with relation to the dominant function: to disregard the initial sympathy to see things in subjectivity/logical conclusions)
enfj - initially approaches the world in awareness of/how people work and external personality (even if not interactive or technically surrounded by others), thrives on internal understanding and establishing specific ideas inside their head, easily interacts and participates with the external world and taking action "if it matters", needs to and requires and eventually (if healthily) needs to look at things analytically (with relation to the dominant function: to disregard the initial sympathy to see things in subjectivity/logical conclusions)
esfp - initially approaches the world to take action and participate and work, thrives on personal reaction and perceived self-judgment/reflection and intrapersonal understanding, easily accesses the ability to logically execute (ideas, ambitions, etc.) "if it matters" to them, needs to and requires and eventually (if healthily) establishes specific ideas inside their head with internal & mental abstractions (with relation to the dominant function: consequences of their actions, goals to work for, etc.)
istj - initially approaches the world through an internal understanding of construction and necessity and present action in the most effective ways, thrives on logical execution, easily references their emotions/justifies things to themselves through intrapersonal understanding "if it matters", needs to and requires and eventually (if healthily) search for and be fascinated at a new/variety of ideas (with relation to the dominant function: to be less fixed on the pre-established mental and practical structure and instead invite new seemingly implausible/useless/ineffective possibilities into their life)
isfj - initially approaches the world through an internal understanding of construction and necessity and present action in the most effective ways, thrives on the importance and understanding the generalized emotive effect on others usually relative to themselves, easily works with logic and analysis through impersonal self-justification "if it matters", needs to and requires and eventually (if healthily) search for and be fascinated at a new/variety of ideas (with relation to the dominant function: to be less fixed on the pre-established mental and practical structure and instead invite new seemingly implausible/useless/ineffective possibilities into their life)
istp - initially approaches the world through perceived logic with self-contained independence, thrives on taking action and participating and work in the concrete world, easily understands things internally and mentally with specific ideas inside their head "if it matters," needs to and requires and eventually (if healthily) understands how people work/attention/acceptance (with relation to the dominant function: disregard logic in favor of the consideration of others)

i'm lazy so the rest of these patterns can be appropriately applied to enfj, enfp, and entj
