You should get a part time job on the weekends at a place that employs or deals with a lot of girls.
That way, you'll make a little money instead of spending it, you won't be drinking, and you'll have a fresh batch of targets every hour or so. You could date a co-worker, or make friends with one and have her set you up with some of her friends.
I've always wanted to get myself some pointless job like that just to meet different/random people/girls. Maybe when you do this, you can come back here and tell me about it so that I can experience it vicariously.
We could be friends and everything. What'd ya say?
