What items do you find so interesting from those companies? In my experience, they mainly sell trinkets. Lower price, but also lower quality. Plus, certain safety risks probably aren’t consistently monitored. If I were to order something related to food preparation, I’d always be worried about BPA, etc.
Schopenhauer “wisdom of life” has good sessions on hapiness, in relation to money and assets. Its an easy read too, for a philosopher.
Life is all about money. Don't let anyone tell you differently. If you already have the yellow gold Rolex and 2 million dollar residence and 100K vehicle and attractive girlfriend.... Double it. Then Triple it. Then Quadruple it. He who has the most when he dies wins. It's like primal human nature and basic psychology and shit
