Here is a quote I like by Os Guinness.
“The overall lesson of insatiability is that money alone cannot buy the deepest things we desire. Money never purchases love, or eternity, or God. It is the wrong means, the wrong road, the wrong search. That is why the pursuit is vanity. ‘Nothing gained’ is the final lesson of insatiability.
Yet the pursuit continues. We keep upping the ante. The horizon recedes as we approach. We still don’t stop. As Sam Walton’s wife Helen admitted, ‘I kept saying, Sam, we’re making a good living. Why go out, why expand so much more? The stores are getting farther and farther away. After the seventeenth store, though, I realized there wasn’t going to be any stopping it.’
When John D. Rockefeller, Sr., was asked how much money it takes to make a man happy, he gave the immortal reply, ‘Just a little bit more.’ It is always over the next horizon, after we’ve conquered the next summit. It’s always tomorrow.”
