“A breed apart from the diarists who write simply to collect the days or preserve impressions of foreign places are those who set out in their books to discover who they really are. These are generally very serious people, more in the way of pilgrims, with inward destinations, than mere travelers. Some of them are after the sight of God; others are out to realize their full ‘potential,’ spiritual and otherwise; and some of them are carrying burdens of suffering they are unsure they can shoulder—they want to use their diaries to test, and add to, their strength.”
