It took me years of my life (between part-time jobs and such) to learn how to properly be a NEET, manage my own time, and put effort into meaningful hobbies and projects that bring me life satisfaction and dopamine hits. It really is a skill and it doesn't come naturally to us, especially when our entire lives are spent doing things within the structure of larger institutions like work and school that hand down our tasks to us.

Now I have a full-time job though and it feels pretty good, as much as I've had to put most of my hobbies on the chopping block.
