A politician needs the ability to foretell what is going to happen tomorrow, next week, next month, and next year. And to have the ability afterwards to explain why it didn't happen.

Forethought we may have, undoubtedly, but not foresight.

A bird is like an instrument working according to mathematical law, and it is in the capacity of man to reproduce such an instrument.

Get up tomorrow early in the morning, and earlier than you did today, and do the best that you can. Always stay near me, for tomorrow I will have much to do and more than I ever had, and tomorrow blood will leave my body above the breast.

It is always wise to look ahead, but difficult to look further than you can see.

I always avoid prophesying beforehand, because it is a much better policy to prophesy after the event has already taken place.
