“Hints to Young Men” (from The Youth’s Companion, 22 November 1849; p. 120)
Always have a book within your reach, which you may catch up at your odd minutes. Resolve to edge in a little reading every day, if it is but a single sentence. If you can give fifteen minutes a day, it will be felt at the end of the year. Regulate your thoughts when not at study. A man is thinking even while at work. Why may he not be thinking about something that is useful? Revolve in your mind what you have last been reading.
