I learn to read some more bass tabs. Cook new pastries which is really one of my frustrations too. lol!
Aha, that's a good one thing that you can do with all of these stays at home times. I envy you because you can do baking, while, I can't. Aside from reading things to improve everything you want to like skills or informative stuff that can enrich your thinking.
Playing PC games is also a good activity to ease boredom.
