I think the best things in life are the things you appreaite, which tend to be the free things because peope don't go looking for them :)
I do believe the best things in life are free, but when we get used to having those "best things" we don't pay as much attention to them, and instead look to the things we would like to have. That's when money comes in to play, at least for most of those extra things we would like to have.
When my two year old grandaughter puts her arms around my neck and squeezes tight... When i share an experience withmy wife... when you're sitting quietly by a river and a platypus appears and gives you the honour of ignoring you...
I don't know the answer to this but the best and most essential things in life SHOULD be free.
you can be rich in many ways, although cash does pay the bills.
