Practice makes perfect
Everything worth doing in life requires practice.
Malcolm Gladwell talked about the 10,000 hours of practice required to truly master any skill.
The good news is you can get pretty decent at stuff in way less time than that.
But that's just another example of the Pareto Principle (a.k.a. the 80/20 rule) in action. The last 20% of skill mastery will take 80% of your time & effort.
An argument for loving what you do, if I ever heard one.
