“You cannot see the past that did not happen any more than you can foresee the future.”

“Look back over the past, with its changing empires that rose and fell, and you can foresee the future too.”

“Do not become so attached to any one belief than you cannot see past it to another possibility.”

“Your past cannot stop you from a bright future, but an improper interpretation of your past can be fatal to your future.”

“You cannot change the past. All you can do is change the way you allow the past to affect your present and future.”

“You, yesterday, did the usual things, just as any day, You don't know if it's worth remembering. You would prefer to remember, there lying in the half-darkness of the bedroom, not what has happened already but what is going to happen. In your half-darkness your eyes would prefer to look ahead, not behind, and they do not know how to foresee the past.”
