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.

So I'd better stop my whining and help myself cope better with even the worst Adversities.

Humans can always accept themselves unconditionally.

Thinking rationally is often different from "positive thinking," in that it is a realistic assessment of the situation, with a view towards rectifying the problem if possible.

The emotionally mature individual should completely accept the fact that we live in a world of probability and chance, where there are not, nor probably ever will be, any absolute certainties, and should realize that it is not at all horrible, indeed—such a probabilistic, uncertain world.

Self-esteem is the greatest sickness known to man or woman because it's conditional.

The best years of your life are the ones in which you decide your problems are your own.
