This revelation came to me rather recently. And it helped me immensely when it came to improving my performance in basketball.
I have always played with people older than me, a lot better than me. And so I rarely touched the ball. This instinctively pushed me to get better — I wanted to touch the ball. And so I got better. A lot better. Very quickly.
The same can work with literally any field. In any area, this simple technique will allow you excel very fast.
