Which of these proverbs are true? explain why. 1) books and friends should be few but good. 2) There is no royal road to learning. 3) Knowledge is power. 4) wise men learn by other men's mistakes; fools by their own.

I think it is true that wise men learn by other men's mistakes but fools by their own.

People have gained much knowledge and experience in all spheres of life. And when they want to make something new, they usually learn what has already been done in that direction. This is the main principle of the world development.

A wise person has the intuitive thinking. So, before taking a new action, he/she analyses what other people did or said in similar situations. In other words, he/she learns their bad and good experiences. As a result, there are no big mistakes and troubles to anyone.

Fools do not waste their time on any analyses. They mainly act spontaneously without thinking about the consequences. It usually ends in failure and bad memories.
