You guessed it…the worst evaluator of your performance is…you yourself. We all have a tendency to set a high value on our self-worth while typically devaluing our weaknesses. Mark Cuban, the outspoken (and very rich) owner of the Dallas Mavericks had a great post about this on his blog recently…
"…I learned a lot from Don Nelson when he was coach and GM of the Mavericks. He told me something early on, that opened my eyes. I forget the exact conversation, but we were talking about players, and I asked him why he didn’t talk to a specific player about something that was going on. What he said was that “The worse evaluator of talent is a player trying to evaluate himself.”
