“We are all only mortal," said the Master, even more slowly. "We do only what we can do. All the Elemental priests have certain teachings in common: one of them is that everyone, every human, every bird, badger and salamander, every blade of grass and every acorn, is doing the best it can. This is the priests' definition of mortality: the circumstance of doing what one can is that of doing one's best. Only the immortals have the luxury of furlough. Doing one's best is hard work; we rely on our surroundings because we must; when our surroundings change, we stumble. If you are running as fast as you can, only a tiny roughness of the ground may make you fall.”

“We can only do the best we can with what we have. That, after all, is the measure of success: what we do with what we have.”

“But in the end, we can’t live our lives by ‘what if’ and ‘if only.’ We can only do the best we can to the best of our ability based on what we know. That’s why the truth is so important.”

“What we can do, we must do: we must use what we are given, and we must use it the best we can, however much or little help we have for the task. What you have been given is a hard thing--a very hard thing... But my darling, what if there were no one who could do the difficult things?”

“We can't any of us do all we would like, but we can do our best for every case that comes to us, and that helps amazingly.”

“The remarkable thing we have is a choice every day regarding the attitude we will embrace for that day. We cannot change our past...we cannot change the fact that people will act in a certain way. We cannot change the inevitable. The only thing we can do is play on the one string we have, and that is our attitude.”
