I struggle with this as well. I joined Toastmaster and this is rewarding as I jumped in as vp of
PR for my club (training, conferences,etc) but have not met anyone yet for dating purposes.
I believe that when I am looking from someone it doesn't happen. It is hard not to be looking but maybe you know what it means. I am staying out of bars and clubs for now because of obviouse reasons.
I don't do the online thing as I had limited success with this medium altough my friends do well (2 got married via match.com) - You may want to try that.
Volunterring when I lived in Atlanta 7 years ago was a hot way to meet people.
Single parties are okay.
I feel that God will provide me with the right person when I am ready. Although, I think I should make more of an effort; sadly the last thing I need right now is a relationship. But the solitare life gets old.
Good luck, keep a positive atitude, dress for success and keep an open mind.
