Words of encouragement are very effective tools whose effectiveness, we usually do not realize. If someone you know is having a bad day a good word of encouragement can help to lift their mood and encourage them.
It leads to the formation of good friendships and strong bonds among individuals while promoting an environment of positivity. Your words can change someone's life. For example, complimenting someone on their artwork can motivate them to carry on making art or simple compliments when someone is trying something new like a new sport can encourage someone to work harder at that sport.
We feel that our words do not matter or that words can only be used to hurt others but the opposite is also true, we must realise that our words have the power to break someone down or build someone up, so we must realize the power in words and use them to help others . A great scholar once said that the "pen is mightier than the sword" and this is a very accurate statement to represent the power of words
