Motivation

Motivation is the youngest idea in this collection — it enters use as a psychological term only in the twentieth century. Older writers describe the same thing with a different vocabulary: will, duty, habit. That difference in words hides a difference in assumption. Motivation is understood as a state that comes and goes; habit as something built regardless of the state.

Read the quotes here with that in mind and they separate quickly into two groups. One promises a feeling — drive, momentum, energy. The other recommends bypassing the feeling and beginning anyway. The second group is older, rarer, and judging by the fact that it has survived centuries, probably the more reliable of the two.
