His domestick habits, so far as they are known, were those of a severe student. He drank little strong drink of any kind, and fed without excess in quantity, and in his earlier years without delicacy of choice. In his youth he studied late at night; but afterwards changed his hours, and rested in bed from nine to four in the summer, and five in winter. The course of his day was best known after he was blind. When he first rose he heard a chapter in the Hebrew Bible, and then studied till twelve; then took some exercise for an hour; then dined; then plaid on the organ, and sung, or heard another sing; then studied to six; then entertained his visiters, till eight; then supped, and, after a pipe of tobacco and a glass of water, went to bed.

Samuel Johnson, in a famous essay on biography, shows the importance of minute particulars: how they bring a person to life and create reader interest:
It is frequently objected to relations of particular lives, that they are not distinguished by any striking or wonderful vicissitudes. The scholar who passed his life among his books, the merchant who conducted only his own affairs, the priest whose sphere of action was not extended beyond that of his duty, are considered as no proper objects of public regard, however they might have excelled in their several stations, whatever might have been their learning, integrity, and piety. But this notion arises from false measures of excellence and dignity, and must be eradicated by considering that, in the esteem of uncorrupted reason, what is of most use is of most value.
It is, indeed, not improper to take honest advantages of prejudice, and to gain attention by a celebrated name; but the business of the biographer is often to pass slightly over those performances and incidents which produce vulgar greatness, to lead the thoughts into domestic privacies, and display the minute details of daily life, where exterior appendages are cast aside, and men excel each other only by prudence and by virtue. The account of Thuanus is, with great propriety, said by its author to have been written that it might lay open to posterity the private and familiar character of that man, cujus ingenium et candorem ex ipsius scriptis sunt olim semper miraturi, whose candour and genius will to the end of time be by his writings preserved in admiration.
There are many invisible circumstances which, whether we read as inquirers after natural or moral knowledge, whether we intend to enlarge our science or increase our virtue, are more important than public occurrences. Thus Salust, the great master of nature, has not forgot, in his account of Catiline, to remark that his walk has now gone quick, and again slow, as an indication of a mind revolving something with violent commotion. Thus the story of Melancthon affords a striking lecture on the value of time, by informing us that, when he made an appointment, he expected not only the hour but the minute to be fixed, that the day might not run out in the idleness of suspense; and all the plans and enterprises of De Wit are now of less importance to the world than that part of his personal character which represents him as careful of his health, and negligent of his life.
But biography has often been allotted to writers who seem very little acquainted with the nature of their task, or very negligent about the performance. They rarely afford any other account than might be collected from public papers, but imagine themselves writing a life when they exhibit a chronological series of actions or preferments; and so little regard the manners or behaviour of their heroes that more knowledge may be gained of a man’s real character, by a short conversation with one of his servants, than from a formal and studied narrative, begun with his pedigree and ended with his funeral.
— Samuel Johnson, Rambler #60, October 13, 1750
In his preface to Letters of Theodore Dreiser (1959), edited by Dressier scholar Robert H. Elias, Elias, who knew Dreiser personally, noted that letters “that simply record data, biographical or bibliographical, or that are primarily love letters” had been excluded. My former therapist, Ralph Colp, Jr., said up front, without hesitation, that this was a mistake, a serious omission. I agreed.
I happened once to mention to Dr. Colp the Penguin series of biographies: Brief Lives. I had purchased one of them. Dr. Colp said that a brief life leaving out most or many important details amounted to an insufficient biography. I realized that he was right.
