In order to keep himself at the top of his condition, to obtain complete mastery of all his powers and possibilities, a man must be good to himself mentally; he must think well of himself.
The secret of success lies in that old word, 'Drudgery,' in doing one thing long after it ceases to be amusing; and it is 'this one thing I do' that gathers me together from my chaos, that concentrates me from possibilities to powers, and turns powers into achievements.
The great aim of your life should be to keep your powers up to the highest possible standard, to so conserve your energies, guard your health, that you can make every occasion a great occasion.
