If the whole point of starting your own business is because you want to get out of the ‘rat race’, doesn’t it need to at least pay your bills? Otherwise, you are still in the rat race, just with even less time.
I don't see all businesses as a rat race. Tech is. The business that I've been building skills towards starting is a fun hands-on product, which involves a bit of artistry and a fair amount of labor and materials costs, and brings people joy. Tech can keep paying my bills, unless my side project gets bigger than I foresee. And if I lose money, I made some nice art along the way and had fun learning new skills.
Sure, but then I am confused as to why the mention of 'the rat race' at all. If your business is a fun hobby, then it is unrelated to you having to still be in the rat race. It would be no different than taking up reading or photography as a hobby. You are still in the rat race, you just also have a hobby.
