Life can only be understood backwards; but it must be lived forwards.
I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.
Why didn't I learn to treat everything like it was the last time. My greatest regret was how much I believed in the future.
You realize that our mistrust of the future makes it hard to give up the past.
It's amazing how a little tomorrow can make up for a whole lot of yesterday.
Never be afraid to trust an unknown future to a known God.
You can't stop the future You can't rewind the past The only way to learn the secret ...is to press play.
Yesterday is gone. Tomorrow has not yet come. We have only today. Let us begin.
The future depends on what you do today.
The past is always tense, the future perfect.
