I have curated the following list of books that you can find in Amazon for purchase. I have used these in various capacities throughout the years with great results.
Disclosure: I have an affiliate marketing relationship with Amazon. I get paid a small commission if you buy any of the books I recommend by clicking on them from my site. I never recommend a book that I have not read myself and found helpful. The books I recommend have helped me tremendously and I hope they do the same for you.
