Somebody else just emailed me asking basically the same question, and looking for my advice. My immediate thoughts were:

- Do you need a cofounder immediately, or can you just try and do less. I know that's easier said than done, but scale back your projects into what you think the most important pain/solution is and focus on that, and see if you can get some traction. It will be easier to convince someone else to join you if you can get some traction.

- Similarly: don't look for people to take a big leap, break it into smaller steps. Do you know anyone who would do something for an evening a week. Or hack on something at the weekend. Treat it more as a fun side-project, and people might be more excited about getting involved. Then once they are in, and you have some momentum, try and grow the committment (that's basically what we did).
