Answer 2

Action speak louder than words

This is a famous proverb which refers we must do and show anything istead of saying just in a mouth. We must try to do instead of saying louder in mouth. Similarly, we must think whatever we say, but we should do instead of saying louder than words.

The same with the mind, by the word, by the action we must prove that we can do it.

Those who do not work and show, do not they just called “non-confidential" of work, they only think, they become pessimistic saying in words, they couldn't do that work in action.

There is a proverb called “for ever action there is a reaction” also we must think before speaking anything. We must boldly tell the things which we can do instead to saying the things which can't be done in louder words.
