If people stopped looking on their emotions as ethereal, almost inhuman processes, and realistically viewed them as being largely composed of perceptions, thoughts, evaluations, and internalized sentences, they would find it quite possible to work calmly and concertedly at changing them.

Life is indeed difficult, partly because of the real difficulties we must overcome in order to survive, and partly because of our own innate desire to always do better, to overcome new challenges, to self-actualize. Happiness is experienced largely in striving towards a goal, not in having attained things, because our nature is always to want to go on to the next endeavor.

Humans can always accept themselves unconditionally.

You mainly feel the way you think.

There are three musts that hold us back: I must do well. You must treat me well. And the world must be easy.

There are three musts that hold us back: "I must do well. You must treat me well. And the world must be easy." And I sometimes think that as long as we keep the second must, which is socially learned, then some screwballs 100 years from now will manufacture atomic bombs in their bathtub and maybe annihilate the whole human race because they demand that the rest of the world must agree with their dogmas. When we don't agree, they may zap us.

The goal...is not to change your desires and wishes but to persuade you to stop demanding that you absolutely must have what you wish-from yourself, from others, and from the world. You can by all means keep your wishes, preferences, and desires, but unless you prefer to remain needlessly anxious, not your grandiose demands.
