First post in a long time. I don't even remember my old username. Been in an LTR, out of it, now. Back in the game and WOW, has it changed.
But here's what works for me. It worked at 32, and it works now at 38.
Go solo. Always.
But go someplace to DO SOMETHING. Don't go to a bar to drink alone and look at girls, don't go to a club to stand around alone and look for girls to dance with. That makes you look pathetic.
Go to an art gallery. Go to a book signing. Go to a concert. Go to a rodeo. Go snowboarding. If you're somewhere having a good time -- and NOT looking around to get laid -- you will meet girls. Women like guys who are fun.
Seriously, wherever you go, don't be looking around scanning for chicks. Women spot that action a hundred yards away and you are dead in the water when they see you on the hunt, especially if you're older. If you're having fun and you talk to a girl who's also having fun -- hey! You're 90% of the way there. Lock up a date and then close the deal. It also helps close the age gap if you meet while doing something you both enjoy.
The plus side is, if you go out to do something you enjoy and you DON'T meet any girls, then you still did something you enjoy. No more "wasted nights."
