It does not matter how slowly you go as long as you do not stop.

Thought is the wind, knowledge the sail, and mankind the vessel.

Perseverance is failing 19 times and succeeding the 20th.

Do tomorrow's work today, and today's work this very moment; the moment may pass in an instant — then when will the work be done?

If you aren't going all the way, why go at all?

Things do not happen. Things are made to happen.

You are not here merely to make a living. You are here in order to enable the world to live more amply, with greater vision, with a finer spirit of hope and achievement. You are here to enrich the world, and you impoverish yourself if you forget the errand.

Do your work with your whole heart, and you will succeed - there's so little competition.

Do not wait; the time will never be 'just right.' Start where you stand, and work with whatever tools you may have at your command, and better tools will be found as you go along.

I never knew a man come to greatness or eminence who lay abed late in the morning.
