Yeah, and even horrible people like Hitler and all them had families and friends and all that. So, while that is true, I think there are exceptions to the rule.
But, "improving" myself wouldn't feel right to me, since that'd just be me being vain, and trying to please society. I like who I am, and I do eat well, exercise and learn new things every day. I'm a friendly, talkative person by nature, yet everywhere I go I'm just kind of off on my own. I joined clubs back while I was in school, and I've joined a couple in college as well -- never really did much, despite trying to be active in them.
I do try to distract myself, and some things do help, but a lot of things don't really take a lot of focus, so even if I'm totally engrossed in something, my mind is going off on 50 different tangents at the same time.
