This is a quote from Mother Theresa whose faith and philosophy we could all learn from. This is a particular favorite of mine and one I try to follow. It has also helped me through many hard times.
People are often unreasonable and self centered
Forgive them anyway.
If you are kind people may accuse you of ulterior motives
Be kind anyway.
If you are honest people may cheat you
Be honest anyway.
If you find happiness people may be jealous
Be happy anyway.
The good you do today may be forgotten tomorrow
Do good anyway.
Give the world the best you have and it may never be enough
Do your best anyway.
For you see in the end it was between you and God
It was never between you and them anyway.
– Mother Theresa
