But it's true. Entrepreneurship is the only thing apart from investment that can make you rich. It's just chances are very low. But it's next to impossible to do that as an employee, even for a C-suite, with a few exceptions.
If you do it to get rich though one needs to become a bit of an investor first. And then ask the question: is my growth potential higher than the companies (on the stock market that have a fair/low price) that I believe in?
