There are no mistakes. The events we bring upon ourselves no matter how unpleasant are necessary in order to learn what we need to learn whatever steps we take they're necessary to reach the places we've chosen to go.

Real leadership means tackling tough problems ourselves and not leaving them to our children.

There is no international problem that can be addressed or solved without the engagement and leadership of the United States and everybody in the world knows that its just fact of life. So sometimes I think we could conduct ourselves with a little more humility.

Imparting knowledge is only lighting other men's candles at our lamp without depriving ourselves of any flame.

We read deeply for varied reasons most of them familiar: that we cannot know enough people profoundly enough that we need to know ourselves better that we require knowledge not just of self and others but of the way things are.

If we don't empower ourselves with knowledge then we're gonna be led down a garden path.

We cannot stop natural disasters but we can arm ourselves with knowledge: so many lives wouldn't have to be lost if there was enough disaster preparedness.

There's a period of life when we swallow a knowledge of ourselves and it becomes either good or sour inside.

We can't have full knowledge all at once. We must start by believing then afterwards we may be led on to master the evidence for ourselves.

Knowledge is of two kinds. We know a subject ourselves or we know where we can find information upon it.
