It's CONFIDENCE...PERIOD. Big dick/small dick, tall/midget, rich/poor, jacked/skinny, ripped/fat...it's all about CONFIDENCE wherever you're at. If you're fucked up skinny/fat, well I guess maybe try getting jacked/ripped...chances are that won't help, but try anyway, you might learn a few things on the way that may lend indirectly to your self-esteem...it's all a journey and the concept of superiority/inferiority due to physical parameters is pretty much moot if you take a look at all the people getting out of life what they want...I mean it might be relevant, or it might not. In the end, successful is as successful does and it's all a matter of how you perceive the person you're calling successful.
