Albert Einstein leaves us a timeless teaching:

Watch what you say.
Don’t give your emotional power to just anyone.
Be silent when the truth may turn against you.
And remember that wisdom is not about knowing everything, but about choosing well what to share and what to keep for yourself.

“Weak people take revenge, strong people forgive and intelligent people ignore.”

Perhaps, in that final sentence, is contained the whole essence of what a wise man – like Einstein – wanted to say to the world.
