A good friend of mine shared this piece of gold with me. It lays out an outline of free projects, courses, and classes you can work on, at your own pace. If you want to learn more about Python and Data Science, this will give you an idea of where to start - https://github.com/ossu/data-science
I started with a Linear Algebra class this week with my friend. He's more of a programming hobbyist than I am, with a series of math related programming problems he finds on Project Euler. Definitely a good way to match with someone who has this kind of mindset and curiosity.
