We learn from our mistakes, we do some reflection, we lick our wounds, we brush ourselves off - then we go forward, with the presumption of good faith in our fellow citizens.
If I had to give you one piece of advice, it would be this: don’t be intimidated by other people’s opinions. Only mediocrity is sure of itself, so take risks and do what you really want to do. Seek out people who aren’t afraid of making mistakes and who, therefore, do make mistakes. Because of that, their work often isn’t recognized, but they are precisely the kind of people who change the world and, after many mistakes, do something that will transform their own community completely.
Arguments from authority carry little weight – authorities have made mistakes in the past. They will do so again in the future. Perhaps a better way to say it is that in science there are no authorities; at most, there are experts.
That a man can take pleasure in marching in formation to the strains of a band is enough to make me despise him. He has only been given his big brain by mistake; a backbone was all he needed.
It is a mistake, too, to say that the face is the mirror of the soul. The truth is, men are very hard to know, and yet, not to be deceived, we must judge them by their present actions, but for the present only.
Man has little needs and deeper needs. We have fallen into the mistake of living from our little needs till we have almost lost our deeper needs in a sort of madness.
We ask for happiness but what we get is unhappiness. We all put our efforts into trying to be happy but we make a fundamental mistake: happiness is not related to the effort, happiness is related to not asking for it.
I think, not only Al Qaida have an ideology; they have tactics necessary to spread their ideology. And it would be a huge mistake for the United States to leave the region, to concede territory to the terrorists, to not confront them.
That is the trouble with many inventors; they lack patience. They lack the willingness to work a thing out slowly and clearly and sharply in their mind, so that they can actually "feel it work." They want to try their first idea right off; and the result is they use up lots of money and lots of good material, only to find eventually that they are working in the wrong direction. We all make mistakes, and it is better to make them before we begin.
