Apparently there was some study that showed that if you’ve met your needs for a roof over your head and ample food, there is no correlation between money and happiness. That is, you aren’t necessarily more happy with more money.
The interesting thing is that most people tend to want more. I think people think they will be happier. Initially they may be, if they got a lot more money. You can have a bigger house, a nice boat, etc. But when the excitement ends, you’re still the same person you were, and you would react to things the same way. If you had existential unhappiness before, you’ll probably have existential unhappiness after.
As for a life free of complications, I wouldn’t wish that on anyone! Complications are character-building. Being able to overcome obstacles gives one a sense of accomplishment and confidence for facing future challenges.
But yeah, simplicity is bliss. A good thing to keep in mind. I wouldn’t know where to start, to simplify. Maybe decluttering some.
