1. On the road of scientific exploration, a person has taken detours and made mistakes. It is not a bad thing, let alone a shame. One must have the courage to admit and correct mistakes in practice. ——Einstein

2. An individual is weak, just like Robinson Crusoe. Only when he is with others can he accomplish many things. ——Schopenhauer

3. Experience can make us avoid detours and help us grow. We must first change ourselves and eliminate all bad factors before we can enjoy the joy of a better life that success brings us.

——(USA) Ruth Rosie
