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.

If you would stop, really stop, damning yourself, others, and unkind conditions, you would find it almost impossible to upset yourself emotionally - about anything. Yes, anything.

By honestly acknowledging your past errors, but never damning yourself for them, you can learn to use your past for your own future benefit.
