Reading your post, you actually sound like quite a thoughtful person @donistered . And the fact that you have self esteem issues - and I can relate to that - is probably the only reason why you believe yourself to be a contemptible person.

Just stick to the path you're on, try not to over-analyze too much, and give yourself a pat on the back for having some good principles to go on, okay dude? You've got your head screwed on right for a 24 year old.
