Have a life outside of the startup. You really shouldn't talk business 24x7. Some investors are assholes about women. Some investors have scar tissue from other couples. That is largely an incorrect view - when founders that are just friends break up a company, there is no reason to hate friends who are founders. My rubric for picking a wife was more rigorous than picking a cofounder could possibly be. I have no idea how people find cofounders beyond long-term friends.
