Write a book. I have never made $1 million writing a book. But I have a number of friends who have made millions writing books or information products of some sort. This is a tricky area, so the key here is that you have to be legit. Don’t write a book on a subject you know nothing about. Then you’re just like one of those BS e-mail spammers, except a hundred times worse because what they do in six hundred words you do in sixty thousand. Instead, partner with someone who knows something and write about what they did.
