“The fact that the biosphere responds unpredictably to our actions is not an argument for inaction. It is, however, a powerful argument for caution, and for adopting a tentative attitude toward all we believe, and all we do. Unfortunately, our species has demonstrated a striking lack of caution in the past. It is hard to imagine that we will behave differently in the future.We think we know what we are doing. We have always thought so. We never seem to acknowledge that we have been wrong in the past, and so might be wrong in the future. Instead, each generation writes off earlier errors as the result of bad thinking by less able minds--and then confidently embarks on fresh errors of its own.We are one of only three species on our planet that can claim to be self-aware, yet self-delusion may be a more significant characteristic of our kind.”

“We are responsible for what we are, and whatever we wish ourselves to be, we have the power to make ourselves. If what we are now has been the result of our own past actions, it certainly follows that whatever we wish to be in the future can be produced by our present actions; so we have to know how to act.”

“Let each of us examine his thoughts; he will find them wholly concerned with the past or the future. We almost never think of the present, and if we do think of it, it is only to see what light is throws on our plans for the future. The present is never our end. The past and the present are our means, the future alone our end. Thus we never actually live, but hope to live, and since we are always planning how to be happy, it is inevitable that we should never be so.”

“We need to ask God for forgiveness and do all we can to correct whatever harm our actions may have caused. Repentance means a change of mind and heart—we stop doing things that are wrong, and we start doing things that are right. It brings us a fresh attitude toward God, oneself, and life in general.”

“We have a right to decide how we want our bodies to look and feel, but unfortunately we do not exercise these rights. Instead, we tend to drift along, victims of our own ignorance of the fact that we can have what we want, if we are willing to take that first step toward developing the self-discipline to govern our thoughts.”

“We cannot change our past. We can not change the fact that people act in a certain way. We can not change the inevitable. The only thing we can do is play on the one string we have, and that is our attitude.”
