I've noticed myself becoming more open to criticism, more comfortable with failure as a learning process...
The longer the training montage, the more dramatic the transformation.
Now I'm doing a thing where I fail constantly and then have men explain to me exactly how and why I failed. Challenging!
These skills feel broadly applicable.
Humility, receptivity, patience, accepting losses, recognizing the difference between risk mitigation and risk aversion, tempering my ego.
