One of the more constructive things I’ve done this year is learning a new language. After taking Spanish in high school years ago, I’ve started over using the free Duolingo app. The exercises are great in the way you can do as much or as little as you’d like.

At 5094 XP, that puts me in the top 8%. This is one of better accomplishments of last year.
I started at the beginning of the pandemic and haven’t missed a day. One of the cool stats they keep is your daily streak. I’m currently at 276, and it feels like I’ve learned a lot. You must complete at least one lesson daily to maintain your streak, that provides a lot of motivation.
The lessons are broken out into themes such as people, places, and family. In each lesson you are reading, listening, speaking, and writing. Once things go back to normal, I ought to be able to survive for at least a little while in a Spanish speaking country.
