Seems to me that people have a hard time realizing and/or accepting how better the pros are then them.
Possibly, and your post made me think about it.
When I was 30 I won a NM state racquetball tournament.
I thought I was a pretty big fish,,, one day while attending a pro event (as a spectator) I had the opportunity to play (if you could call it "with" him) a few points with the #3 player in the world at the time. Turns out I wasn't a big fish,, I was plankton.
Honestly, it wasn't until that moment that I really KNEW how massive the gap was between world #3 and me. I knew this to be true intellectually, but not so firmly in my gut.
It still boggles my mind many, many years later.
