“
Here is the prime condition of success, the great secret -- 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. Finally, do not be impatient, for as Emerson says, 'No one can cheat your out of ultimate success but yourself.'
