Fear is often humiliating, because once it is recognized as unfounded, one has to admit to wasting opportunities that will never come again. Then one thinks about how much one does not do because of this feeling which, if it is not cowardice, has an undesirable restrictive effect. No one feels at ease when faced with the image of a worse future; however, the means of glimpsing it are so precarious that it is almost always best not to worry.
