If you have a rational mind, you have to catch up with it. You don't have to worry about what you are doing. Do you want to laugh when others are watching it, you don't need to use it either. People have been born for dozens of years. For example, if the year is light, they are afraid that the wolf will be afraid of tigers and will not be able to catch up with each other, when you reach the age of 40 and 50, the only thing you can do is to feel the loss of the age of the month...

 

It is safe to dock a ship in a harbor, but this is not the purpose of shipbuilding.

If you want to have stronger self-control, you must have more self-consciousness.
