What exactly are you looking for? Another technical cofounder? A business person? Etc.. Finding different types of people require different approaches because the market isn't even.
What I can't seem to do is connect with people at the level that brings about trust that something can be accomplished. I attend start-up events and am held back by my own...I don't know...fear of rejection, lack of belief in myself, leftover trauma from being the fat kid in elementary school? It's hard to psychoanalyze myself.
I knew it was a ghost of a chance because I don't even know what I'm really getting at, beyond what does it take for you to feel confident somebody is, well, competent and his/her idea is worth listening to.
Honestly, I feel like I'm missing something in this interaction because I have technical skill (15+ years), I have business skill (5+ years), I have management skill (5+ years), and I have product management skill (3+ years). I know how to get shit built, but I can't figure out how to get people interested in building it, much less on board.
This isn't criticism -- most people aren't builders either.
So I guess the question I'm left with is: do you want advice on how to get better at attention-drawing and leadership, or are you looking for another human to supplement your skills?
Either path is valid, it just depends on how you want to expend your energies, and what sorts of practicalities require consideration.
There's things like http://sideprojectors.com where you can showcase your project and find a cofounder on, or you can try to go on sites like FounderDating.com|founder2be.com|builditwith.me|etc, or head out and work on your projects at MeetUp groups in your area. There are several options, however I don't know the best way that works for you.
