Absolutely. I started out doing jui jitsu when I was a kid and then switched to wrestling around middle school. I got pretty good in high school, but I couldn’t ever get past my mental game. I was always in my head thinking about things that had no real relevance to my improvement. And so, to use your language, I couldn’t ultimately overcome my ego. But because of the tools those kinds of sports (or martial arts or whatever) gave me, it definitely has helped me to keep learning how to sort through and gain insight into ego later in life.
