No.
Seriously, wtf are you talking about? Give a specific example.
For a more concrete example, I'm sure lots of us liked to play sports growing up. I sure did, anyway. When highschool rolled around, though, I realized I was never going to be a pro or even play in college.
Being an 'athlete' was a part of my identity -- it wasn't easy to just walk away from. Instead, I turned to weightlifting (not Olympic

).
Weightlifting wasn't a real replacement. It didn't allow for direct competition, for one thing. As a result, I travelled off into a fantasy world where I could still consider myself 'athletic'.
Anyway, just one example where I held myself back by holding on to the past, all so I could avoid a harsh truth.
