I was talking with a couple of developer friends about how it's difficult to assess your own skill ceiling by looking at other examples. I used Hellen Keller as an example, but I think BrolyLegs is a more modern and relatable one.
Due to his condition, he could only play using his face. He was the #1 Chun Li player at Street Fighter 4, and he even reached #25 at EVO in Street Fighter 5 (where all the world's best players compete).
He reminded us that limits are bullshit.
