“Anyway”

People are unreasonable, illogical, and self-centered,
LOVE THEM ANYWAY

If you do good, people will accuse you of
selfish, ulterior motives,
DO GOOD ANYWAY

If you are successful,
you win false friends and true enemies,
SUCCEED ANYWAY

The good you do will be forgotten tomorrow,
DO GOOD ANYWAY

Honesty and frankness make you vulnerable,
BE HONEST AND FRANK ANYWAY

What you spent years building may be
destroyed overnight,
BUILD ANYWAY

People really need help
but may attack you if you help them,
HELP PEOPLE ANYWAY

Give the world the best you have
And you’ll get kicked in the teeth,
GIVE THE WORLD THE BEST YOU’VE GOT ANYWAY (source).

Added line from another version:

You see, in the final analysis, it is between you and God;
It was never between you and them anyway.
