Pittsburgh entered the core of my heart when I was a boy and cannot be torn out.

The secret of happiness is renunciation.

Immense power is acquired by assuring yourself in your secret reveries that you were born to control affairs.

Here is the prime condition of success: Concentrate your energy, thought and capital exclusively upon the business in which you are engaged. Having begun on one line, resolve to fight it out on that line, to lead in it, adopt every improvement, have the best machinery, and know the most about it.

The greatest astonishment of my life was the discovery that the man who does the work is not the man who gets rich

The problem of our age is the proper administration of wealth, so that the ties of brotherhood may still bind together the rich and poor in harmonious relationship.

The man of wealth [should] consider all surplus revenues which come to him simply as trust funds, which he is called upon to administer to produce the most beneficial results for the community - the man of wealth thus becoming the mere trustee and agent for his poorer brethren, bringing to their service his superior wisdom, experience and ability to administer, doing for them better than that they would or could do for themselves.
