Sometimes this is true. I've started several side projects to learn a new programming language. So I created 2-3 projects with the different frameworks, never feeling guilty if I should give up or restart with a different approach. But the 4th time, though, it just "clicked", and I'm launching a new project with a new programming language + framework soon, and I intend to monetize it on day 1.

If I have very few customers, it's a portfolio project. If I have a bit more, it'll break even and I can dedicate some time to it. If it grows even more, I'll try to make a business out of it.
