But high stress can do some amazing things to your brain. And immediately when I found this out I use it at my advantage. For years I worked on my project with results like "a step forward, two steps behind". So I quit my job with only a few thousands $$ and put as much stress on my "system". I found my "eureka moment" a few days before I ran out of $$. They call this the survival instinct.

I think it's great that you succeeded but you shouldn't generalize your experience. I also put everything on the line for a business idea and failed miserably with a lot of debt. There are a lot of factors involved in success. It's not only persistence.

Stress usually comes with health issues. Be careful
