Well, either that or crimes, but some crimes can be seen as illegal work

Human existence requires work. Someone has to grow the food, someone has to fix the things, someone has to build the structures and plumb them and someone has to help fix us when we get broken. The only way to never work is to freeload off of everyone who is working.

What really sucks is that society expects us to be “specialists” in one thing for the rest of our live

Specialization is literally how humanity shifted from being hunter-gatherers who lived to be about 30-40 before getting mauled by a bear or killed by another tribe or dying of an infection because you slipped on a rock.

In the modern economy specialization doesn't have to mean doing the same thing every day. Any kind of career where you fix things, you can easily find a job that varies wildly from day to day. A mechanic might be replacing an engine cylinder one day and rebalancing wheels the next and rebuilding the exhaust the next. An IT person can be troubleshooting a software error one day then tweaking network performance the next then imaging laptops the next. A project manager will have different work depending on what phase of the project it's in, and the type of challenges and work will vary wildly by what kinds of projects they're managing

The trick is, find something you don't mind doing and that can turn into finding something you kinda enjoy. As long as you don't wake up dreading work every day (which if you do it's probably time to shake things up, both for yourself and for your loved ones!) you can have a pretty decent life
