It probably that thick wad of cash you keep in your front pocket, either that or some form of cured Italian meat, if you know what I'm TALKiNG ABOUT!!!
Girls love a good combination of the following: - self-confidence, - humor (you can mess around and be a jerk but be careful to not cross the line), - romantic commitment to one person only (this means waiting for someone to reply when you ask her out before you ask anyone else), - BIG[\b], toned muscular body (the whole body! don't neglect any one muscle especially legs and upper back; leg workouts provide a good influx of testosterone which will help muscle recovery and growth following the workouts that come after) - thoughtful, serious consideration, - and instantaneous reactions. Other advice (this may involve quitting KaW): tl;dr: Time is money. Get off your chair and work for what you want. All good things don't just come in time. They come in the time that you make for yourself. If you've been spending all your free time playing KaW, then what the hell are you doing asking others about how to make women like you? Such a thing is pointless considering how far behind you are. tl;dr: It's never too late for a change. Still, don't fret over wasted time. Everyone is a dark horse with potential. As long as you have the ability to breathe, get out there and work for what you want. You can become a late bloomer. Look at pictures of puberty transformations posted by girls on Instagram and Facebook. Look at guys you knew in high school who were fat and cute and became quite muscular and manly later in their mid-20s. People are driven to change.
