The best age for men is 10 years between 40 and 50. There are many things to do, and you can do it if you want, but slow down. Only when you slow down can you enjoy this best decade. You should do what others ask you to do before the age of 30. After the age of 30, you should study your own affairs in a muddleheaded way. At the age of 40, you must know your strongest and favorite things. At the age of 50, you should do something for young people.
