Practice makes perfect. This proverb is very simple. However, the simple does not mean easy. Because we usually do not know how to practice and how much we need. I have the answer how much. The answer is 10000 hours for to get job, 10 years for being professional. As for how to practice, I am still trying to find the best way.

But I do love the music, not just for listening, for playing. But to enjoy playing instruments, I need to practice. The key is habit. I heard that even professional musician practice playing with in 30 min. Why? Because we can do every day if only the practice is 30 min. The point is that we need to practice every day. That is very difficult. We have many excuses, and music is not work, that means practice is not obligation. O.K. Lets start practice only 30 min everyday, shall we?
Japanese business man are often told that they should take time for 30 mins to 1 hours to learn something other than work. That is good idea. The person who keep learning 30 mins everyday becomes someone when he becomes 30 years old. Since almost Japanese starts job around 22 years old, they would have some skills which he would learning 8 years.

I will change the subject. I happened to find the book “Race Against the Machine: How the Digital Revolution is Accelerating Innovation, Driving Productivity, and Irreversibly Transforming Employment and the Economy“. I have just ordered this book on amazon.com. But, I think that I will find some answer which I have been searched for. The answer would tell us that we are going to lose against the machines. We have to change the strategy.
One of my best book I have read is “How Life Imitates Chess: Making the Right Moves, from the Board to the Boardroom” by Garry Kasaprov. He is best chess player in the history. However he was defeated by IBM supercomputer Deep Blue in a game of chess, that happened just 15 years ago. After I knew the fact, I started to think differently.
The happiest story is, as workers age population growth, the number of jobs increase. But why is American GDP growing, but unemployment rate is stable. Why Japanese GDP is merely (Haha) growing, even the workers population is decreasing. I have not confirmed yet, maybe is machine taking our job? I am going to survey more.
As for physics, there are quite a few region that we can beat machine. However, I have to always think which task may be taken by machine.
