Those that only take a nibble here and a nibble there will never attain anything ... Those who really want to be yogis must give up, once and for all, this nibbling at things. Take up one idea. Make that one idea your life - think of it, dream of it, live on that idea.
Stamping down the weakness of mind and heart, stand up, saying, "I am possessed of heroism, I am possessed of a steady intellect..." Never allow weakness to overtake your mind.
Excellence is never an accident. It is always the result of high intention, sincere effort, and intelligent execution; it represents the wise choice of many alternatives - choice, not chance, determines your destiny.
It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; . . . who at best knows in the end the triumph of high achievement, and who at worst, if he fails, at least fails while daring greatly.
