Against the beautiful and the clever and the successful one can wage a pitiless war but not against the unattractive: then the millstone weighs on the breast.

I have no doubt that we will be successful in harnessing the sun's energy. If sunbeams were weapons of war we would have had solar energy centuries ago.

I was lucky enough to lead a very successful war.

The rule for effective governance is simple. It is one Ronald Reagan knew by heart. And one that he successfully employed with Social Security and the Cold War. When there is a problem you fix it. That is the job you have been sent to do and you cannot wait for someone else to do it for you.

The most successful war seldom pays for its losses.

Man approaches the unattainable truth through a succession of errors.

There are very few human beings who receive the truth complete and staggering by instant illumination. Most of them acquire it fragment by fragment on a small scale by successive developments cellularly like a laborious mosaic.

To enjoy enduring success we should travel a little in advance of the world.

Air travel survived decades of terrorism including attacks which resulted in the deaths of everyone on the plane. It survived 9/11. It'll survive the next successful attack. The only real worry is that we'll scare ourselves into making air travel so onerous that we won't fly anymore.

I think that somebody with the resources and innovation and the idea is going to come out of nowhere and come up with a successful space travel program.
