Philosophers have explained space. They have not explained time. It is the inexplicable raw material of everything. With it, all is possible; without it, nothing. The supply of time is truly a daily miracle, an affair genuinely astonishing when one examines it. 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. A highly singular commodity, showered upon you in a manner as singular as the commodity itself!
For remark! No one can take it from you. It is unstealable. And no one receives either more or less than you receive.
You have to live on this twenty-four hours of daily time. Out of it you have to spin health, pleasure, money, content, respect, and the evolution of your immortal soul. Its right use, its most effective use, is a matter of the highest urgency and of the most thrilling actuality. All depends on that. Your happiness—the elusive prize that you are all clutching for, my friends!—depends on that. Strange that the newspapers, so enterprising and up-to-date as they are, are not full of “How to live on a given income of time,” instead of “How to live on a given income of money”!
— Arnold Bennett. His book
How To Live on 24 Hours A Day is kind of the original self-help (from 1910!) and you can
read it for free in email installments here. I probably reread this book about once a year whenever I get a case of the “There’s never any time!”s.
