Context: Success means doing the best we can with what we have. Success is the doing, not the getting — in the trying, not the triumph. Success is a personal standard — reaching for the highest that is in us — becoming all that we can be. If we do our best, we are a success. Success is the maximum utilization of the ability that you have.

Context: Religious people often say that religion offers absolute certainty about right and wrong; "god tells them" what it is. Even supposing that the aforementioned gods exist, and that the believers really know what the gods think, that still does not provide certainty, because any being no matter how powerful can still be wrong. Whether gods exist or not, there is no way to get absolute certainty about ethics. Without absolute certainty, what do we do? We do the best we can. Injustice is happening now; suffering is happening now. We have choices to make now. To insist on absolute certainty before starting to apply ethics to life decisions is a way of choosing to be amoral.
