Hi, Jon! Just wanted to share the latest interesting thing I’ve heard about the money: money —are just the multiplier. I.e., if you are happy, they can make you happier. If you are unhappy, more money will make you even unhappier. That’s why it’s so important to be happy person without (independently of) money/success/external factors.
There is also a TED Talk by Shawn Achor: The happy secret to better work — he also explains, that happiness is prior success, not behind. Take a look if haven’t yet.
Best regards!
