Spend better
Three principles for spending your money to make you happier from the excellent titled paper "If money doesn’t make you happy then you probably aren’t spending it right."
- Buy experiences instead of things.
- Help others instead of yourself.
- Buy many small pleasures instead of a few big ones.
If I feel like I have money and I'm not feeling so happy, the tips from this paper come to mind, and I find myself reflecting on what I could be doing differently with my money.
More generally, I believe there is a correlation between money and happiness, but only up to a certain level, at which point most of our needs are met, and more money doesn't tend to make people that much happier.
