I've always loved this quote, attributed to Mother Teresa:
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.
I always feel more joy when I am living my life to please myself, my family and most importantly, my Heavenly Father. When we worry what other people are going to think of our actions, it often stifles our willingness to be better, to reach out and to grow. Like this quote says, no matter what we do, it will never be enough to impress everyone. So, why don't we stop trying? Easier said than done, I know, but why don't we all work on it together...
