Winston Churchill: Illuminate

“A man can wear out a particular part of his mind by continually using it and tiring it…[and this tired part] can be rested and strengthened, not merely by rest, but by using other parts. It is not enough merely to switch off the lights which play upon the main and ordinary field of interest; a new field of interest must be illuminated…It is only when new cells are called into activity, when new stars become lords of the ascendant, that relief, repose, refreshment are afforded.”

—Winston Churchill.
