One of my most important goals is not to inundate the reader with a thousand principles at the beginning. It has turned me off of many textbooks. Expensive ones I felt I had to get for university. To be honest, the best way to get going is the one that will make you feel as though you are making progress. There's nothing like banging your head against a brick wall to make you walk away. With that in mind, I would recommend you don't go through these guides until you've grasped a few of the lessons. I don't want you to feel you need to read anything here during the start of your journey. However, you will eventually need to read them.
