I have spent many years observing the peculiar ways in which the human mind torments itself, and I confess that I have been both student and subject in this matter. The anxieties that plague us in our daily existence are perhaps as old as consciousness itself, yet we persist in believing that each worry is unique, each fear unprecedented. How curious it is that we should think ourselves so original in our suffering when, in truth, the same basic concerns that troubled our ancestors continue to disturb our sleep today.
