How do you know what you want?
noodle: i do what i know i enjoy doing until i don't enjoy doing it anymore.  lather, rinse, repeat.it usually is just that simple.  your list of things you enjoy doing will shift as you grow, experience, and learn.  you're wasting your own time and energy worrying about the "what if"s.  either give something new a shot, or continue doing what you're doing."what if i'd like being a scientist better" or "what if i'd like starting a startup better".  either go find out, or stop worrying about it, because its wasteful on many levels.its been working out for me so far.
