The chief beauty about time is that you cannot waste it in advance. The next year, the next day, the next hour are lying ready for you, as perfect, as unspoiled, as if you had never wasted or misapplied a single moment in all your life. You can turn over a new leaf every hour if you choose.
You wake up in the morning, and lo! your purse is magically filled with twenty-four hours of the unmanufactured tissue of the universe of your life! It is yours. It is the most precious of possessions.
And since nothing whatever happens to us outside our own brain; since nothing hurt us or gives us pleasure except within the brain, the supreme importance of being able to control what goes on in that mysterious brain is patent.
