How Frank Wilczyk Teachs Himself Machine Learning

How does Frank Wilczyk teach himself machine learning? Do you have like a systematic approach to self-directed learning and what sort of like sources are you consulting? It's system. I have a pilot, but it's the same way as I learned physics or anything else. I talk to people who have more knowledge. In this case, I've listened to a couple of online courses and I look at books and I see which books are good.
