"Write often, write upon a thousand themes, rather than long at a time, not trying to turn too many feeble somersaults in the air,--and so come down upon your head at last. Antaeus-like, be not long absent from the ground. Those sentences are good and well discharged which are like so many little resiliences from the spring floor of our life,--a distinct fruit and kernel itself, springing from terra firma. Let there be as many distinct plants as the soil and the light can sustain. Take as many bounds in a day as possible. Sentences uttered with your back to the wall. "
