It is a mistake to try to look too far ahead. The chain of destiny can only be grasped one link at a time.

If we open a quarrel between past and present, we shall find that we have lost the future.

Plans are of little importance, but planning is essential.

Of this I am certain, that if we open a quarrel between the past and the present, we shall find that we have lost the future.

The empires of the future are the empires of the mind.

Do not let spacious plans for a new world divert your energies from saving what is left of the old.
