I free myself from fear of the unknown.

Almost everyone can confirm this from their own records: the appointment is easier than the fortnight before it. The interview lasts forty minutes and the dread lasted nine days. The conversation you rehearsed eleven times took four and went fine.

The unknown is where the mind does its worst work, because it has been asked to fill a space containing no facts, and it fills it with the only material available.

Once a thing is actually happening it becomes finite. Awful, sometimes. But finite, with a floor, and with you already in it and coping.
