The less a man knows about the past and the present, the more insecure must prove to be his judgment of the future.

Real generosity toward the future lies in giving all to the present.

The future comes like an unwelcome guest.

My interest is in the future, because I am going to spend the rest of my life there.

Do not boast about tomorrow, for you do not know what a day may bring.

Destiny is not a matter of chance, it is a matter of choice; it is not a thing to be waited for, it is a thing to be achieved.

I don’t try to describe the future. I try to prevent it.

It would be madness, and inconsistency, to suppose that things which have never yet been performed can be performed without employing some hitherto untried means.

The world began without man, and it will end without him.

Every man takes the limits of his own vision for the limits of the world.

I like the dreams of the future better than the history of the past.

God seems to have left the receiver off the hook, and time is running out.

The future is no more uncertain than the present.
