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

“There are times in our lives when we have to realize our past is precisely what it is, and we cannot change it. But we can change the story we tell ourselves about it, and by doing that, we can change the future.”

“We should do nothing for revenge, but everything for security: nothing for the past; everything for the present and the future.”

“Our moods change constantly and thus our ideas about the past change with them. As for the future, it remains unwritten. Anything can happen, and often we are wrong. The best we can do with the future is prepare and savor the possibilities of what can be done in the present.”

“The past is the one thing we are not prisoners of. We can do with the past exactly what we wish. What we can't do is to change its consequences.”

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