Re: dance. My current cardio routine is improv dancing and it's definitely a lot of fun. Re: drilling. This applies in any domain, even programming. Pick small problems and do variations on them until they become second nature. It's a surprisingly effective way to learn. Gary Bernhardt has actually turned this idea into a product with Execute Program: https://www.executeprogram.com/.

I suspect there are a few untapped product ideas here for programmers still. I'd be willing to pay for a set of drills in learning the various AI frameworks. The theory is linear algebra + calculus which can be learned alongside the drills for the framework and could potentially be another set of drills.
