"So greatness isn’t handed to anyone; it requires a lot of hard work. Yet that isn’t enough, since many people work hard for decades without approaching greatness or even getting significantly better. What’s missing?

The best people in any field are those who devote the most hours to what the researchers call ‘deliberate practice.’ It’s activity that’s explicitly intended to improve performance, that reaches for objectives just beyond one’s level of competence, provides feedback on results and involves high levels of repetition.

For example: Simply hitting a bucket of balls is not deliberate practice, which is why most golfers don’t get better. Hitting an eight-iron 300 times with a goal of leaving the ball within 20 feet of the pin 80 percent of the time, continually observing results and making appropriate adjustments, and doing that for hours every day – that’s deliberate practice."

"Armed with that mindset, people go at a job in a new way. Research shows they process information more deeply and retain it longer. They want more information on what they're doing and seek other perspectives. They adopt a longer-term point of view. In the activity itself, the mindset persists. You aren't just doing the job, you're explicitly trying to get better at it in the larger sense.

Again, research shows that this difference in mental approach is vital. For example, when amateur singers take a singing lesson, they experience it as fun, a release of tension. But for professional singers, it's the opposite: They increase their concentration and focus on improving their performance during the lesson. Same activity, different mindset.

Feedback is crucial…. Without it…. If you don't know how successful you are, two things happen: One, you don't get any better, and two, you stop caring."
