Yes. It’s pretty damn obvious that money, or at least more than a sufficient amount of money, can make you happier.
Imagine not having to stress about bills and rent/mortgage. Imagine just being able to go wherever you like and do whatever you like, because you can afford it.
Want to do something fun but costly? No problem. Go ahead and have that fun.
Want to eat well? Well, that costs money. Have all that organic unprocessed food cooked well without a thought.
Want to be healthy? Not worrying about money will lower you stress levels, and you can afford that gym membership or personal trainer, fitness classes, yoga, etc.
Experiences and goods become accessible because you can afford them.
The only thing is is I wouldn’t recommend buying a submarine trip to see the Titanic.
