The greatest discovery of my generation is that a human being can alter his life by altering his attitudes.

Truth is what will be steadily borne out by subsequent experience

Results should not be too voluntarily aimed at or too busily thought of. They are sure to float up of their own accord from a long enough daily work at a given matter.

The simplest rudiment of mystical experience would seem to be that deepened sense of the significance of a maxim or formula which occasionally sweeps over one.

Plasticity, then, in the wide sense of the word, means the possession of a structure weak enough to yield to an influence, but strong enough not to yield all at once. Each relatively stable phase of equilibrium in such a structure is marked by what we may call a new set of habits.

The most violent revolutions in an individuals beliefs leave most of his old order standing. Time and space, cause and effect, nature and history, and ones own biography remain untouched. New truth is always a go-between, a smoother-over of transitions. It marries old opinion to new fact so as ever to show a minimum of jolt, a maximum of continuity.

Most unhappiness is caused because people listen to themselves... instead of talking to themselves.
