I think it's a bit of a pessimistic take, to be sure, but I do agree that most people will not make it through this in a self-directed manner. Sure, some may, and I wish the OP the best and hope it all works out, but it's hard for most people to tackle much simpler, straightforward topics in a self-learning environment.

In this case, though, I think OP's approach to this shows that they're serious about keeping with it, which is really cool to see.
