The 10,000-Hour Rule says that you need approximately 10,000 hours of practice to become a world-class expert in a field. There is no other way: if you want to be a world-class expert in your field, you must do your 10,000 hours of practice.一万小时天才理论说的是：要想成为这一领域的世界级专家，你就需要花大约一万个小时来练习。没有其他的法子，如果你想成功，那就必须得花一万个小时。
Then, where should you invest my 10,000 hours of practice?
This question is important because 10,000 hours is a lot of time. If you consistently practice 4 hours a day for 6 days a week, you will still need 8 years to get 10,000 hours. So answering this question is essential. If you need to invest such a huge amount of time, you’d better do it right. You’d better find your niche.
To find your niche, I find the three questions below helpful. Answer them and you will have an idea of where you should go. Here they are:
1. Where have you invested your time?
One way to know where to invest your time is simply to look at where you have invested your time. For example, in the last few years you might have learned how to play music for one or two hours a day. Or you might have blogged about a certain topic. Or you might have spent a lot of time on gardening.
Those are good signs of where you should invest your 10,000 hours. You already invest part of that 10,000 hours so you only need to invest the rest. The difference is now you do it consciously and deliberately. You will be more effective that way.
2. What are your passions?
In fact, that’s one reason why 10,000 hours is a magic number to become a world-class expert: almost everyone else fails before reaching that point. Only a few people can reach the 10,000 hours mark and that’s why they become world class.
To help you reach the 10,000 hours mark, doing something you love is really helpful. It will help you go through difficult times. It will help you overcome boredom. Without it, the 10,000 hours will feel like a painful journey. It’s highly unlikely that you will ever reach the 10,000 hours mark that way。
3. What opportunities does the age give you?
Ask yourself: what opportunities does your birth date give you? What opportunities does the history give you at this point in time?
Answering these questions is not easy because it’s difficult to see whether or not something will be hot. When Bill Gates did his 10,000 hours of practice to learn programming, he might not know that it would eventually put him in a perfect position to be a software mogul. You need to have faith in something and believe that the dots will eventually connect.
