Best (and fast) way to learn Houdini

Hi there! Im a multidisciplinary artist with experience with other software (Cinema 4D, touchdesigner etc.). Houdini will be perfect for my workflow and that's why I want to learn it. I have tried some video tutorials and only understood the basics. But now I want to dive into this amazing program. What is the best way to learn Houdini? Patreon and which creator? Courses? Private lessons?
