The popular belief is that to become good at something, you have to invest 10,000 hours. That’s a full time job for 5 years. Fortunately, it is not true. If you want to become the very best of the best, and excel in a highly competitive field, you need to invest 10,000 hours of focused practice. But, according to Josh Kaufman’s TEDx talk, you only need 20 hours to learn pretty much anything you can think of, from business skills to sports to playing the ukelele.
For most of the skills you need, in business and in life, being proficient is all that is necessary. You don’t have to be the best in the world, just good enough to do what you need to do.
