Does anyone have experienced this:

I could make about 3k - 5k per month with personal projects, but after more than 20 years developing digital products, I've never got to 10k/month for example. It's like a mental barrier. From the outside it seems I just got bored after a project is built and its running.

But internally I know there is something more. Like don't believe I really could make 10k or 20k / month.

Why do you think I cannot break this barrier? What would you recommend?
