I don't care if you're stuck at 2.0 or pushing 3.0. It's just semantics.
The most successful people I know don’t question themselves — but they do question their knowledge. They see asking for advice as a way of testing their ideas, which makes those ideas better and helps them learn.
Similarly, I watched the billionaire Mark Cuban mention on Shark Tank that he makes his business decisions based on return on time rather than return on investment.
To the entrepreneur, success is learning, not execution.
