Yes actually. Based on some of the Quora answers I've read, they don't enjoy cooking after coming home. But since cooking is an unavoidable activity (unlike a side project, you can't procrastinate with hunger) they might have to.
That's crazy. Everyone should be free to do whatever they want in their own free time.
>it's doing the same when you get home
That's what my colleague answered me when I asked him "why don't you have side projects?". Everyone should be able to choose whatever they want to do with their own free time.
I don't consider a side project as "the same thing I do at work", and I don't consider myself special.
