I can't make this more simple for all of you:
Take two individuals who are being total fuck ups:
--The ESFP is the one who is fucking up because they are having too much fun or being too active
--The ENFP is the one who is fucking up because they are just not too concerned about the future...and swear that they have xyz scheme that will totally fix everything.
If they arent fuck ups yet, just imagine which category they'd fall into.
appendix section: take two individuals who you know are ENF, but you aren't sure if they are ENFJ or ENFP:
--the one who is more ESTP-like at times is ENFJ
--the one who is more ESFP-like at times is ENFP
