There are many ways in which you can make money with WordPress. Creating a website for the purposes of promoting a business or selling goods through an online store is one such way. Monetizing a blog with display ads is another. While there are other ways in which you can use your WordPress site to make money, perhaps one of the easiest ones to get started with is affiliate marketing.
Regardless if you need to earn some fast cash or we're just talking about making money in the grand scheme of things, there's an important psychology that needs to be mentioned before getting into the strategies. If you study Freud's model of the mind, you'll discover the Psychic Apparatus. It's the three-part construct in your mind that controls all of your behavior.
