This.
I have a friend who is like 400 pounds, but is the most charismatic mother fucker ever. Dude gets mad amounts of vagina.
Edit**
Just wanted to add something here. Probably like 2 years ago my self confidence was real low. I had just got done vegging out on WoW. I thought my social skills were horrid, I felt like I was a fat bastard, and I though I was ugly lulz. I mean I could talk to girls, but it just went no where, and I"m in college. I started hitting the gym. I started losing weight and putting on some muscle, but more importantly it just made me feel better about myself. It gave me the confidence I needed. I mean I"m no Aychamo or anything, but now it"s me turning the chicks down, not the other way around.
Switch your game up is what I"m trying to say. If you aren"t confident with yourself, change yourself. Make yourself happy... or don"t and be unhappy, it"s all in YOUR head.
