You’re falling for that propaganda too, a little bit; as are we all. We don’t need to be productive every moment of the day - hell, studies have shown that humans are only really productive about 4 hours out of the day. If you work a 9-5 style job, 4 hours of every day is spent doing things other than being productive. So don’t feel guilty for doing things just because they make you happy. Play video games, make Warhammer models, do silly little drawings that only you will ever see, whatever makes you happy, simply because that’s what life is about: doing things that make us happy. Time spent doing that is never time wasted, and screw the people that tried to convince entire generations that we only have worth as a person if we’re being “productive.”
