[ Singles & Dating ] Open Question : Ok, now I need of advice!?

1) I suck at looks and I can't do anything about it as I'm Sikh (In my religion, we are not allowed to cut our hair, look it up on google if u dont know about it)...so I'm pretty low on self-esteem, how to have more self-confindence? 2) I like this girl in my class, who is in my leaugue, we hv had convos on fb once or twice...but I let the convo die...how to keep it upbeat and alive? 3) How to ask her out?
