You can do this every day, in a hundred ways.
Why not practice it with the first three people you encounter after reading this?
It is really a very easy thing to do — yet it can affect a person mightily. All you have to do is look for the best in that person, and then show it to them,right then and there.
Describe it. Admire it. Thank them for it.
Do this for three people every day and watch how your whole life can change.
At last you will realize what you are doing here. All the rest will be just stuff and nonsense.
