Effortless and costing nothing, kind words are easily forgotten by the speaker. It was really nothing. Yet to the recipient, these kind words, at the right time and place, can uplift spirits sufficiently to allow them to continue their life, no matter the difficulty. We need more of these kind words, so spread the word.
What does it take to be nice to someone when you could have been equally harsh? At times words that correct bad actions are needed, and in the end will greatly benefit the receiver. They may not like it at the time, but hopefully they will appreciate the time and effort it took you in order for them to improve.
There are times when the other person is under stress and going through an unfortunate experience. Say some kind words. While you may not be able to directly change the situation, nice words from you might increase their morale such that they can continue to do the job they need to do.
With kind words you might be repaid in kind in the future. We all go through tough times and you certainly will appreciate it when, in your tough times, you receive some kind words.
It has always been my belief that if everyone acted for each other, the same amount of energy would be consumed overall but the level of happiness would skyrocket.
Example being holding a door open for someone.
Total energy used is actually less than if the door was passed onto the next person to hold open. The marginal amount of energy for the door holder is usually minimal, but significantly lower anyways. Given that the recipient is appreciative, both parties have now gained a +ve in their lives.
If this was extended to many more things and situations, it’s easy to see how doing something for another, and having someone do that for you in return works wonders.
