Oh i didn't mean to imply that, Im just saying, it's understandable they'd be a bit concerned. Truth be told, I'm European so I'm not familiar with the American educational system (and college here is pretty affordable), so I understand that there are different and possibly higher stakes for you.
Helping people is good - now the question becomes, is it practical help (think nurses), advise and problem solving (think doctors), inspirational and creative help (think art/film/writing/..), and so on. Once you narrow that down, it's a matter of which medium/specialization has always drawn you the most (psychiatric nurse, oncologist, film maker, etc) and how do you want to go about that specialisation - are there perhaps several you'd want to fuse together and in what way?
Nobody says you have to lock in those options yet, but it's nice to examine them and cut the chaff from the wheat so you actually have a manageable buffet of options instead of an avalanche.
The idea is to play to your own strengths, stay away from things that will deplete your energy and find that thing that will always inspire/sustain/intrigue you. I too love learning in general, and I always want to learn more about different fields so I can get an overview and compare and contrast between them, but that is driven by my core which is understanding living beings, to help them more, so the thing I always come back to is 'how do other see/experience the world?' The things I've studied allow me to navigate the world while asking that question a lot easier (writing= learning how to communicate, learning different languages= idem ditto, psychology= understanding their make up and reasoning, ethology = idem ditto for animals, etc). It's the one thing I'm interested enough in to want to actually master, whereas the rest I'm more than happy to just have a workable knowledge of.
