However, we (and I include myself here) have a bad tendency not to follow this obvious little tip -- in life as a whole, and in golf in particular -- so I wanted to post it.
This tip is from page 143 of The Wisdom of Harvey Penick, and it's simply called "An Irony":
In golf your strengths and weaknesses will always be there. If you could improve your weaknesses, you would improve your game.Not much I can add to that. Guess I'll go work on my weaknesses for a while.
The irony is that people prefer to practice their strengths.
