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

“Don't ever think I fell for you, or fell over you. I didn't fall in love, I rose in it.”

“It was never too late to learn something. The past is unalterable in any event. The future is the only thing we can change. Learning the lessons of the past is the only way to shape the present and the future.”

“The present changes the past. Looking back you do not find what you left behind.”

“You can't change the past, but you can ruin the present by worrying about the future.”

“The past always seems better when you look back on it than it did at the time. And the present never looks as good as it will in the future.”

“If you could not accept the past and its burden, there was no future, for without one there cannot be the other, and […] if you could accept the past you might hope for the future, for only out of the past can you make the future.”

“You can't look back - you just have to put the past behind you, and find something better in your future.”

“A world of "if"s, but it would make no difference. If I could go back in time… but I couldn't. The past was behind me. The best thing now would be to stop looking over my shoulder. It was time to forget the past and look to the present and future.”

“Nothing we do can change the past, but everything we do changes the future.”
