No one going to pick on the violinist? Hard not to understand his point, but no points for gracefully accepting a little adulation.

Most of us worry about money until we hit point x; where that point is often defined by how much time, effort, or stress we'd have to endure to go further. Happiness might be defined as knowing when you have enough. I find that the trap most people fall into (including me occasionally) is that enough seems to keep moving upward and then you're just on the treadmill. Are you happier than you were five years ago? Why not? Will another $10k really make you happy?

To go on about money for a moment, I think it's less about what you make than what you owe. There's a lot to be said for saving the money and then buying whatever thing you need (two exceptions are buying a first home and student loans).
