When we talk practice, We're not suggesting that you need
to beat golf balls until your hands bleed.
You need to have a plan for “Deliberate Practice”. 

Geoff Colvin, who’s also a golfer, wrote the book
“Talent Is Overrated: What Really Separates
World-Class Performers from Everybody Else”.

He talks about the need for “Deliberate Practice”
and its very powerful impact on performance improvement.
