John Wooden

If you are not making mistakes, then you are not doing anything - John Wooden

You can't let praise or criticism get to you.

 It's a weakness to get caught up in either one.

If you're not making mistakes, 

then you're not doing anything.

Whatever you do in life, surround yourself with smart people 

who'll argue with you.
