“Thanks to the way your brain is wired, you're likely to screw over your future in order to stay loyal to decisions you made in the past”

“And if you were always spending your time getting over your past, how were you supposed to get on with your future?”

“You may have created my past and screwed up my present, but you have no control over my future.”

“Stay committed to your decisions, but stay flexible in your approach.”

“While I don't in any way question your honor, your patriotism or your service to our country, I do question some of the decisions, the judgments you’ve made over the past two and a half years. During that time things have gotten markedly and progressively worse.”

“But you only get so many do-overs in this life, so many chances to, if not change your past, alter your future.”

“You aren't your past, you are probability of your future.”

“You're always free to change your mind
and choose a different future, or a different past.”

“Life is in Fate's hands now. You made your choice to stay… it's too late to change that, so stop agonizing over it…. You're making my scales itch.

Saphira, from "Eragon”

“One day you're young with all your fine plans for the future. The next you're in the future and it doesn't look at all the way you thought it would.”
