Aim for the highest.

All honor’s wounds are self-inflicted.

And while the law of competition may be sometimes hard for the individual, it is best for the race, because it ensures the survival of the fittest in every department.

As I grow older, I pay less attention to what men say. I just watch what they do.

Concentration is my motto — first honesty, then industry, then concentration.

Do not look for approval except for the consciousness of doing your best.

Don’t be content with doing only your duty. Do more than your duty. It’s the horse that finishes a neck ahead wins the race.

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.

I believe that the road to pre-eminent success in any line of work is to make yourself master of that line of work.

I can’t afford to pay them any other way.
