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

Persevere towards those objectives which are lighted for us by all the wisdom and inspiration of the past.

The uncertainty and importance of the present reduce the past and future to comparative insignificance, and clear the mind of minor worries. And when all is over, memories remain which few men do not hold precious.

Personally, I am stuck with one foot in the past and one foot in the present.

The stupid speak of the past, the wise of the present, and fools of the future.

I try to learn from the past, but I plan for the future by focusing exclusively on the present. That's where the fun is.
