What do bootstrapped, side-project founders who don't code do for a living?

Seeking replies directly related to non-coding, bootstrapped side-project founders and what you/they do to earn/sustain their living prior to the project becoming self-sustaining.

What are the challenges for you? How much time do you really have left after FTE, family, sleep, and leisure time?

Personally, I'm selling furniture to get by. How about you?
