The only thing we know about the future is that it will be different.

The past is really almost as much a work of the imagination as the future.

Change is the law of life. And those who look only to the past or present are certain to miss the future.

Education is not only a ladder of opportunity, but it is also an investment in our future.

The future enters into us, in order to transform itself in us, long before it happens.

The hardships that I encountered in the past will help me succeed in the future.

True happiness is... to enjoy the present, without anxious dependence upon the future.

We should regret our mistakes and learn from them, but never carry them forward into the future with us.

Yesterday's the past, tomorrow's the future, but today is a gift. That's why it's called the present.

Living in dreams of yesterday, we find ourselves still dreaming of impossible future conquests.
