I myself hated the idea of becoming the boss. I didn't even like to admit that I had employees. I'd talk about them as people who worked with me rather than for me. That wasn't true, of course. It never is.
Someone always has to be the boss, even in a start-up.
If you don't accept that reality, you're headed for trouble. There are actually two types of mistakes that people typically make when they're new to the boss's role. The first involves their relationship with employees. The other has to do with their assumptions about their own job. To be a good boss you need to maintain a certain distance from your employees.
