[Mathew Green]

Similar is this:

People are unreasonable, illogical and self-centered.
Love them anyway.

When you do good, they will accuse you of egoism and ulterior motives.
Do good anyway.

If you are successful, you will acquire false friends and real enemies.
Be successful anyway.

The good that you do will be forgotten tomorrow.
Do good anyway.

Sincerity and openness make you vulnerable.
Be sincere and open anyway.

What you build with years of work can be destroyed in a single day.
Build it anyway.

Your help is really needed, but people may attack you if you help them.
Help them anyway.

Give the world your best, and it will kick you in the teeth.
Give the world your best anyway.
