What are you learning at the moment, and why?

For me it's skateboarding. I picked it up again two years ago after a long hiatus. Doing ollies fast and high is the next best thing to flying. Also, a couple more tricks to master and I can enroll in a course to become an official skateboarding teacher. Lastly, I'm starting to miss learning math. By my next post I better have done something about that.

Curious to see what other people are learning, when the forum has a bit more members :)
Sapere aude!
