Inspirational books and audio programs are one of the best fuel sources for cultivating desire. Nightingale Conant has some of the best. If you want to quit smoking, read a dozen books written by ex-smokers on how to quit the habit. If you want to start a business, then start devouring business books. Go to seminars on occasion. I advise that you feed your mind with some form of motivational material (books, articles, audio programs) for at least fifteen minutes a day. This will continually recharge your batteries and keep your desire impenetrably strong.

When you absorb material created by an extremely passionate person, you'll often find yourself feeling more passionate as well. A great book I read was Pour Your Heart Into It by Howard Schultz, the CEO of Starbucks. As I read the book, I was absolutely amazed at how someone could be so fanatically enthusiastic about coffee. Other enthusiasm-building authors/speakers I highly recommend are Harvey Mackay and Zig Ziglar.
