I'm in pretty much the same situation as you, having done startups before with cofounders and encountered lots of problems related to that. Now I'm a single founder. The problem (at least for me) is that you have to find someone that's smart, gets things done and have the determination required to do a startup. It seems that there are a lot of dreamers that like the idea of doing a startup, but when the rubber meets the road almost all people bail. Not that I blame them, most people have commitments that requires them to hold steady incomes, spend time with family, etc. Finding a good co-founder is almost as hard as doing a startup. There are lots of people that will say yes when you ask them, but very very few that will actually get something meaningful done to move things forward in a serious way.
