Deepest principle of human nature is to be appreciated.

I wished by treating Psychology like a natural science, to help her become one.

The transition from tenseness, self-responsibility, and worry, to equanimity, receptivity, and peace, is the most wonderful of all those shiftings of inner equilibrium, those changes of personal centre of energy, which I have analyzed so often; and the chief wonder of it is that it so often comes about, not by doing, but by simply relaxing and throwing the burden down.

So to feel brave, act as if we were brave, use all our will to that end...and a courage-fit will very likely replace the fit of fear.

It is very important that teachers should realize the importance of habit.

The strenuous life tastes better

We can change our circumstances by a mere change of our attitude.
