Yesterday is history, tomorrow is a mystery, today is God's gift, that's why we call it the present.

Yesterday is gone. Tomorrow may be for us and it may not.

When I talked to him on the phone yesterday. I called him George rather than Mr. Vice President. But, in public, it's Mr. Vice President, because that is who he is.

Cured yesterday of my disease, I died last night of my physician.

I'm a hypochondriac. Yesterday it was brain damage from the vodka the night before. Today, heart attack - my arm and chest started hurting at the same time.

I try to be the same person I was yesterday.

No one should be ashamed to admit they are wrong, which is but saying, in other words, that they are wiser today than they were yesterday.

Learning and innovation go hand in hand. The arrogance of success is to think that what you did yesterday will be sufficient for tomorrow.

I think if you look at yesterday's New York Times poll, particularly when you judge Democrats in Congress versus the Republicans in Congress, people put a little more faith, or even a little more than a little more faith in the Democrats in Congress.

You too must not count too much on your reality as you feel it today, since like yesterday, it may prove an illusion for you tomorrow.

Whatever is a reality today, whatever you touch and believe in and that seems real for you today, is going to be - like the reality of yesterday - an illusion tomorrow.

Today's practicality is often no more than the accepted form of yesterday's theory.

An economist is an expert who will know tomorrow why the things he predicted yesterday didn't happen today.

To feel today what one felt yesterday isn't to feel - it's to remember today what was felt yesterday, to be today's living corpse of what yesterday was lived and lost.

Families are the tie that reminds us of yesterday, provide strength and support today, and give us hope for tomorrow. No government, no matter how well-intentioned, or well-managed, can provide what our families provide.
