I think the best thing anyone can do is not try so hard. You can't will things into existance. Of course you have to try a little. You have to put yourself out there.
But first you need to be okay with yourself first. You need to be able to say "I'm okay being by myself, but I would like someone to share my life with. But if that doesn't happen, I'm still gonna be okay." Sometimes love shows up in the most unexpected places, at the most unexpected time.
Just be yourself, be respectful, have a sense of humour, relax, listen carefully...
Take a class, go for walks (get a cute puppy- that will attract lots of chicks

) - go where people are. Don't be afraid to be rejected- and try not to take it personally.
