I failed at rugby, I tried my best to be a top performer but was unable to ever overcome my anxiety with needing to truly want to hurt the person you tackle. Coming from a long series of no contact sports this was a huge thing for me to overcome, that I had found something that no matter how much effort I put in I would never be as good as others because of a difference in mindset. It taught me that there are some things I'm not geared for. I can still try my best and do well, but there can be situations where certain kinds of limitations prevent you from progressing as you would expect of yourself.
