Hum that's a good question, rebellion or what have u. I workstation a college and have a degree regarding the psychology of the college age adult. Not to bore you, but in essence, college age students like yourself usually are still finding out who they are, what they value, who they want to become in the world. I wouldn't worry about it too much, unless you don't like what you see. If that's the case, maybe take an inventory about what your goals are and what is meaningful to you. How are your current actions and attitudes getting you to reach that goal. If they aren't helping, then how are they hindering you?

Good personal development questions you have mentioned in your post. Good for you for questioning and challenging yourself on them....good luck!
