It would be fun to answer "myself", but I'm a terrible boss.

As a freelancer you're also helpdesk, finance and marketing of your own little company, and I'm horrible at those things.

My current boss lets me boss myself within the company, while I still get to enjoy the luxuries of company life — completely shielded from annoying questions, with a stable predictable income.

I do believe that's the optimal structure: Hire people who can manage themselves, and have a drive to improve the company with minimal oversight.

Don't have true "bosses" at all, just some people who are good at bridging communication gaps between the islands of self-reliant teams.
