That’s a large topic to cover for sure. Sometimes I have the feeling that we live in some sort of consumerist downward spiral. Be more productive. Earn more money. Buy more stuff. Rinse and repeat. One fire is fueling another. I know the short high you get when hitting that „place your order“ button. Amazon is in the lucky position to be at the right time in the right spot offering the right stuff. The question is, why are we there? How did we get there? We rarely ask those. The „why“ in particular. And from there on, we enter absurd territory. „I broke up with someone, so I went and bought some stuff” is more common than we realise. We feel bad, we go buy something. The act itself creates a feeling of achievement (endorphins released? Probably). In a way we are all slaves to our human nature. The amount of gadgets I bought over the years that I never really needed to start with is frightening. And in some ways, it made me even lazier and less creative to own a $2000 SLR Camera and 4 lenses, tripods and flash lights. They all sit in the drawer, waiting to be used. It’s probably similar with your books. There was no thought process involved. Consumption happened on an instinct level. Like “I’m thirsty, need drink”. So we go and get something to drink. Have you ever been shopping for groceries with an empty stomach? How much more crap do you buy if you’re hungry compared to if you’re consciously shopping for healthy food? So in a way, we are always hungry for something when we shop things, trying to fulfill needs and desires with materialism, ergo consumerism. We have to look inside ourselves to try and understand why we do wha we do. And that’s the hard part. Because we soon realise that what bubbles on the surface is probably caused by things that we might not be so eager to look and think about. So we splash another layer of color on top of it and fix the parts that started to show some cracks, knowing that if the coating is off, we become vulnerable or have to face introspection.
TL;DR, think before you buy and avoid impulse decisions. Dig deeper.
