People will say 'well women like confidence and more than just looks', but let's be honest, just looks is very effective and simple to do for 99% of women. Humor / confidence / personality is very subjective - and it's hard to work towards, as opposed to physical appearence.

I'll be upfront - I use anabolic steroids (somewhat responsibly, or as much as I can be with dangerous chemicals), but I still haven't gotten that 'wow damn fuck me' effect on women that girls will have on me just for having the right outfit on.
