It is easy to get discouraged in the world, to feel criticized or broken down and to feel that it is all hopeless. When I feel like that, I find that this quote from Mother Teresa of Calcutta is incredibly helpful and beautiful. It was apparently written on the walls of her Children's Home in Calcutta. Even if you are not religious, I think it has a significance in how one approaches life.
'People are often unreasonable, irrational and self-centered. Forgive them anyway.
If you are kind, people may accuse you of selfish, ulterior motives. Be kind anyway.
If you are successful, you will win some unfaithful friends and some genuine enemies. Succeed anyway.
If you are honest and sincere people may deceive you. Be honest and sincere anyway.
What you spend years creating, others could destroy overnight. Create anyway.
If you find serenity and happiness, some may be jealous. Be happy anyway.
The good you do today, will often be forgotten. Do good anyway.
Give the best you have, and it will never be enough. Give your best anyway.
In the final analysis, it is between you and God. It was never between you and them anyway. '
