Ladies, how can show what I have without seeming arrogant?

Aww you're cute! lol Just be yourself, man. If you don't have a problem talking to women it should be inevitable for you to mention your interests like martial arts or w/e. Just don't throw everything out there in one conversation, that's when you'll come off pretentious lol. Hmm...the other stuff you can gradually mention later as you guys get to know each other. Trust me, she won't forget. As she get's to know you she'll go "Hey, this guy's a catch." So take it easy. And when you get a number call before you text-women like that. (unless someone says she doesn't-then think twice because texts are far more impersonal than a call and she may have some social issues or something, idk.) Hope I've helped =)
