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

Future orientation is combined with a notion and expectation of progress, and nothing is impossible.

The best thing about the future is that it comes only one day at a time.

Your past is not your potential. In any hour you can choose to liberate the future.

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

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.

The best preparation for the future is the present well seen to, and the last duty done.

Times and conditions change so rapidly that we must keep our aim constantly focused on the future.

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