Every noble activity makes room for itself

Intellectual tasting of life will not supersede muscular activity

Health is the condition of wisdom, and the sign is cheerfulness, -- an open and noble temper.

Progress is the activity of today and the assurance of tomorrow

As the gardener, by severe pruning, forces the sap of the tree into one or two vigorous limbs, so should you stop off your miscellaneous activity and concentrate your force on one or a few points

As every man is hunted by his own daemon, vexed by his own disease, this checks all his activity.
