Everything's eventual

I've been doing a lot of thinking about what I want to do with my life, what I want to be when I grow up, even who I want to be when I grow up and the conclusion I've come to is... I still don't know. Is that sad, bad, normal, a problem? I don't know, it just seems like there are so many things I'm interested in that I can't quite pick one so I ended up in the banking profession as a sort of accident rather than really by choice, it's not hard work, the hours are good, my coworkers are, for the most part, pleasant and easy to get along with, oh yeah, there are annoyances of course, I'm rather stressed at the moment and sometimes people seem so stupid you wonder how they made it out of childhood, they should have been killed at some point just to prove Darwin correct but I mean, that's in all professions I think. But I really want a job/profession/whatever that makes me want to go to work in the morning or doesn't require me to be up early in the mornings, where I feel I'm making a difference, at least to my own mental/emotional/spiritual wellbeing yet pays enough to live comfortably, not be rich because I really don't care about that, but have enough money to have a nice place, nice shoes and lots of books and be able to travel, I don't think that's too much to ask for. I just feel so antsy all the time like I s/b doing something specific with my life, like what's it all for, am I just wasting time till I die, most days seem the same and time is passing SO FAST, I'll be 40 in two years and what have I really accomplished, will I be remembered for anything other than my sarcastic comments? I want someone/thing to point me in the right direction and tell me "this is what you s/b doing, go do it".
