Reverend Daark has answered exactly as it should be, so I can't offer anything better than that.

But there are two quotes I like that I've used many times here.

"To rule yourself (that is, to rule your persona by yourself) is greater than to rule the world."

"A person whose genius or other predilection is contributory to the development of any science, art, philosophy or religion as a lifework, having accepted his mission and administering it for the world's weal and his own happiness - he is a world worker."

- Dr. Elmer Gates (1853 - 1923).

Human beings are as significant as a cigarette burn in the sun.
