Anxiety and Expectations

We become most anxious when we have an expectation that is unreasonable.  If we expect ourselves to do what cannot be done it is an unreasonable and unattainable assignment, one at which we can only fail, and in face of that fact anxiety is a reasonable reaction.  The more unreasonable the task, the greater (and more reasonable) is the anxiety we feel.  Better to have expectations that are within our competence.
