Do it anyway.

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 may 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.

- Mother Teresa
