Move faster. This makes your mind pay closer attention in order to avoid mistakes. This demand for increased attention wakes you up, focuses your mind and makes the task more challenging. You can speed up without feeling unpleasantly stressed: Make it like a game. How much can you get done in the next half hour? Set a target and see if you can reach it. This makes a tedious task less boring and, as a bonus, frees up more time for things you like to do.

Listen to something. Everyone knows it’s more fun to do physical work while listening to good music than it is working in silence. Music engages your mind to some degree. But there is something that engages your mind more completely: talking. There has been a virtual explosion in the publishing industry of books and seminars on audiotape. Many people who commute to work have converted that boring and otherwise unproductive time into a mind-engaging education. The amount of material available on tape is staggering. In the next few years, using only the time you spend driving and doing household chores, you can learn a foreign language, listen to countless great books read to you by the best readers in America, and transform boring routines into an opportunity to expand your mind.

There’s another kind of value to tapes. Often it doesn’t matter what you have learned. Even if you could recite it, some practical knowledge matters only if you have it in mind. Ideas about human relations are like that. I have pretty much memorized the principles in Dale Carnegie’s book How to Win Friends and Influence People, but when I am face-to-face with a real human being, I often forget it all. It isn’t fresh in my mind — it’s stored away somewhere. For this kind of knowledge, it’s better to listen to a little every day. Then the ideas will be in the front of your mind when you need them.
