Resonating Graduation Quote

I had the honor of attending my first graduation at my school, celebrating the 45 new Bachelor of Science students in our program as well as other undergrad and graduate students. One of the speeches included this quote, which is often associated with (though not written by) Mother Theresa. I really love it, especially the end, with the reminder about where to ground ourselves - not in others' issues, impressions, expectations, or stories told, but in God, who is truth. Doing this isn't simple or easy, but is satisfying and right.

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 anyone else anyway.
