I think the problem may be that you want to be as "real" as you can with others, which, in your case possibly, takes place by being first real with yourself. Sounds to me like you may see yourself as so imperfect that the closest thing to combatting it is "realizing" it.
Honestly. I mean- I used to share these thoughts. But- I found out: I have potential. Everyone has potential. Nothing's useless. I see so many succeed. I got by without doing much. If I put just a little more effort or, hell, a lot more effort into doing things... hey, I could be great.
