I love this story. And I confirm with everything you just said. I experienced exactly the same. Fun fact. Also with bball.
My story: after my time in the army I actually started to intensively playing bball. I was not super talented. I’m not tall. (6ft). But my new mindset shift and relentless attitude put me in a position to play on a professional level making fiat. This was not possible with my skillset or my body but it was with my mind. A valuable lesson that I learned that way. Keep it up bro 👊🏼
