We shall never have more time. We have, and always had, all the time there is. No object is served in waiting until next week or even until tomorrow. Keep going... Concentrate on something useful.

One of the chief things which my typical man has to learn is that the mental faculties are capable of a continuous hard activity; they do not tire like an arm or a leg. All they want is change - not rest, except in sleep.

We need a sense of the value of time - that is, of the best way to divide one's time into one's various activities.

It is well, when judging a friend, to remember that he is judging you with the same godlike and superior impartiality.

The second suggestion is to think as well as to read. I know people who read and read, and for all the good it does them they might just as well cut bread-and-butter. They take to reading as better men take to drink. They fly through the shires of literature on a motor-car, their sole object being motion. They will tell you how many books they have read in a year. Unless you give at least 45 minutes to careful, fatiguing reflection (it is an awful bore at first) upon what you are reading, your 90 minutes of a night are chiefly wasted.

The only way to write a great book is to write it with the eyes of a child who sees things for the first time.

Your own mind is a sacred enclosure into which nothing harmful can enter except by your permission.
