We have heard this idiom several times. And somewhere in our lives we recognize its accuracy. What you do is more important than what you say. People say many things, make many promises but it’s easy to say and difficult to carry out.

Don’t talk, just act. Don’t say, just show. Don’t promise, just prove. – Unknown

If you want to know or judge a person then you should analyze his words and actions. For instance, if somebody keep on telling his friend the goods and bad of something and himself don’t differentiate between them then he is a double-dealer. This is the approach how people judge each other. If you express your feelings well with your love but do not show them in your doings then the loved one will get confused but if you can’t express well but show your affection this will make your relationship durable. Although words are required as well but if words and actions are poles apart then people will rely on your nonverbal message over the verbal one.

People lie, actions don’t. – Unknown

This idiom “Actions speak louder than words” is valid in all stages of life. It is applicable in every field whether it’s your job or relationships. We meet countless people in our lives and we want to be familiar with some of them, for this purpose we don’t need to do much effort as his actions will tell us whatever we need to know.
I read over the internet:

People may not tell you how they feel about you, but they always show you. Pay attention. – Keri Hilson

Mistakes can be made by anyone and they should be rectified later but if it’s a habit of someone then one should not believe his words but his deeds. We should monitor our actions and our words if they are colliding with each other or not. After all we can strive to become a better person.
