No side project, but some new hobbies (to be good at learning)

Many developers asked me: “what side projects do you do?”

“No, I used to do, but now I don’t”.

Why

Most of the side projects won’t be able to finish. why?

There is no business value. you will be bored.

Most side projects are just repeating another “CRUD” app using a different language, web framework, database, or cache with some fancy-looking structure like “Micro-service”.
