What Is The Best Way To Learn Machine Learning Without Taking Any Online Courses?

What is the best way to start learning machine learning and deep learning without taking any online courses? Let me first start off by saying that there is no single "best way" to learn machine learning, and you should find a system that works well for you. Some people prefer the structure of courses, others like reading books at their own pace, and some want to dive right into code. I started with Andrew Ng's Machine Learning Coursera course in 2012, knowing almost zero linear algebra and nothing about statistics or machine learning. Note that although the class covered neural networks, it was not a course on Deep Learning.
