Based on the writings of William Arthur Ward, a 20th Century optimist and inspirational writer:
I will do more than belong—I will participate.
I will do more than care—I will help.
I will do more than believe—I will practice.
I will do more than be fair—I will be kind.
I will do more than forgive—I will forget.
I will do more than dream—I will work.
I will do more than teach—I will inspire.
I will do more than learn—I will enrich.
I will do more than give—I will serve.
I will do more than live—I will grow.
I will do more than suffer—I will triumph.
Always do what you can where you can.
Few will have the greatness to bend history itself, but each of us can work to change a small portion of events. It is from numberless diverse acts of courage and belief that human history is shaped. Each time a man stands up for an ideal, or acts to improve the lot of others, or strikes out against injustice, he sends forth a tiny ripple of hope, and crossing each other from a million different centers of energy and daring those ripples build a current which can sweep down the mightiest walls of oppression and resistance.” ― Robert F. Kennedy
