I had a recent conversation with a young mentee that mentioned that he lacked confidence at his startup. I couldn't quite respond on the spot how to solve this issue, but here's my thoughts after some thinking and self-reflection.
Find something that you're good at, that you're better than anyone else at, and something that gives you joy everyday.
There are no shortcuts to finding out your 1 thing. It could be tomorrow, or it could be 3 years from now. You just have to keep digging.
Don't close yourself to a new task or a new experience - try it if given the chance. You might just stumble upon what you're really good at.
