If you could "freeze" the entire world except you for 1 year, what would you do with that time?

In other words: what would be most rewarding thing that doesn't depend on others / is not interactive?

(assume physics doesn't pause, e.g. you can still move around, touch things, and access static info on the internet)

I work for Ethereum at the Ethereum Foundation.

Definitely something that requires really long periods of practice: endurance training, meditation, fasting, etc.

first thing would be to learn how to fly a plane

Catch up on art - read, watch, listen, etc

I would love to just walk through many cities.

Code more

Practice soccer + snowboarding and make up for not starting when I was a child

Become fluent in Korean

I would probably keep doing what I do now, code, read and train my body, but with more body training
