“If you believe that feeling bad or worrying long enough will change a past or future event, then you are residing on another planet with a different reality system.”

“To perceive the world differently, we must be willing to change our belief system, let the past slip away, expand our sense of now, and dissolve the fear in our minds,”

“If you can change your mind, you can change your life.”

“Act as if what you do makes a difference. It does.”

“If you wish to upset the law that all crows are black, you mustn't seek to show that no crows are; it is enough if you prove one single crow to be white.”

“We must know the truth; and we must avoid error,--these are our first and great commandments as would-be knowers; but they are not two ways of stating an identical commandment, they are two separable laws. Although it may indeed happen that when we believe the truth A, we escape as an incidental consequence from believing the falsehood B, it hardly ever happens that by merely disbelieving B we necessarily believe A. We may in escaping B fall into believing other falsehoods, C or D, just as bad as B; or we may escape B by not believing anything at all, not even A.”

“These then are my last words to you. Be not afraid of life. Believe that life is worth living and your belief will help create the fact.”
