There must be freedom to lose as well as win.

You can suceed despite, or because of failure.

Failure is part of the human condition, and highly correlated with trying things for the first time.
Failure is not the outcome, failure is not trying

Very capable, smart people - can sometimes not even attempt to act on their great ideas for one reason: They're afraid of failing.

people can try to 
''be-good' ==> The focus is on proving that we have ability and know what we're doing;

''get-better'' ==> The focus is on developing ability. It relieves some of the pressure we put on ourselves to be perfect.

Mistakes don't make you look foolish, but acting like you are a born expert on everything certainly will.
