I think....
confidence, success, and a self belief are what makes someone attractive.
Non of which I possess in any large quantity.
However, there is genetics, but that is not something you can control, but you can make the best of what you've got I guess.
Currently, I am going to the gym, and some of the female staff are paying me compliments. Weirdly enough, some males are too (as I take a few steps backwards, then turn and run).
Anyway, try for the first 3 (confidence, success, and self belief). It you were lucky to get good genetics, then don't abuse it, as attractiveness is as much a asset as cash in the bank. Otherwise, at least do your best to look your best
Note: I think that makes for 10 posts... yippy, I'm in for April!
