Correction does much, but encouragement does more.

Correction does much, but encouragement does more. Encouragement after censure is as the sun after a shower.

Instruction does much, but encouragement everything."

(Letter to A.F. Oeser, Nov. 9, 1768)

The formation of one's character ought to be everyone's chief aim.

It is in human nature to relax, when not compelled by personal advantage or disadvantage.

The older we get the more we must limit ourselves if we wish to be active.
