Wisdom, compassion, and courage are the three universally recognized moral qualities of men.

Obstacles are like wild animals. They are cowards but they will bluff you if they can. If they see you are afraid of them, they are liable to spring upon you; but if you look them squarely in the eye, they will sink out of sight.

Here must all distrust be left behind; all cowardice must be ended.

There will be obstacles. There will be doubters. There will be mistakes. But with hard work, there are no limits.

Almost every significant breakthrough is the result of a courageous break with traditional ways of thinking.

If things seem under control, you are just not going fast enough.

Be brave. Take risks. Nothing can substitute experience.

If you do build a great experience, customers tell each other about that. Word of mouth is very powerful.

The two qualities that chiefly inspire regard and affection [are] that a thing is you own and that it is your only one.

Fast is fine, but accuracy is everything.

Quality is never an accident; it is always the result of high intention, sincere effort, intelligent direction, and skillful execution; it represents the wide choice of many alternatives.

We acquire a particular quality by acting in a particular way.

To understand the true quality of people, you must look into their minds, and examine their pursuits and aversions.

Sometimes when you innovate, you make mistakes. It is best to admit them quickly, and get on with improving your other innovations.

It is a very great thing to be able to think as you like; but, after all, an important question remains: what you think.

Grant me, O Lord my God, a mind to know you, a heart to seek you, wisdom to find you, conduct pleasing to you, faithful perseverance in waiting for you, and a hope of finally embracing you. Amen.

A wise man proportions his belief to the evidence.

In life, all good things come hard, but wisdom is the hardest to come by.

I hope our wisdom will grow with our power, and teach us, that the less we use our power the greater it will be.
