It's not about being happy, happy comes and happy goes; it's about doing something meaningful with your life, because it's the only thing that is going to work long term.
it's about doing something meaningful with your life
This is what I don't understand. Kudos to those who do something meaningful with their life - but why should I do it too? What if I am perfectly happy watching Netflix and sleeping 14 hours a day?
I'm not saying everyone is the same, far from it; there wouldn't be any need to keep billions of us around if we were.
But life doesn't waste opportunities for evolution, and there's no point in having billions of people watching Netflix forever. It will find a way to get you out of your comfort zone, cooperating or kicking and screaming.
