The strong are easy to be strong, just as the weak are easy to be weak. What does this famous saying mean?
The weak have no confidence in themselves, so they can't do anything well, so they are easy to be weak. The strong are just the opposite. With their past success, they dare to try anything boldly and become strong easily. These two different styles are also caused by the same habits. So the weak can become weak and the strong can become strong.
