Have a look at this guy. Makoto Nagano is a Japanese fisherman and was 34 years old when this was shot.
He competed in SASUKE / Ninja Warrior six times before he won, even getting to the final stage and failing by less than a second. He never gave up. That’s how you win.
The incredible upper body strength on display is nothing compared to the mental strength to keep going and push yourself just a bit further.
