Like Charlie Munger once said: “I’ve long believed that a certain system - which almost any intelligent person can learn - works way better than the systems most people use [to understand the world]. What you need is a latticework of mental models in your head. And, with that system, things gradually fit together in a way that enhances cognition. Just as multiple factors shape every system, multiple mental models from a variety of disciplines are necessary to understand that system". You can read this book to start building a "latticework of mental models in your head".

I'd just go with something that's a bit of a more light read, like Dan Kennedy's Ultimate Sales Letter, or Joe Sugarman's The Adweek Copywriting Handbook. Either one of these will give you a solid building block that you can then expand upon with the more advanced courses, like Breakthrough Advertising, or Clayton Makepeace's Ultimate Desktop Copycoach.
Great copy is the heart and soul of the advertising business. In this practical guide, legendary copywriter Joe Sugarman provides proven guidelines and expert advice on what it takes to write copy that will entice, motivate, and move customers to buy. For anyone who wants to break into the business, this is the ultimate companion resource for unlimited success.
