The question is, when is enough, enough? I know people who have "made it" in so many ways, and appear to everyone to be totally successful. But, they are NEVER HAPPY. That is a very important point, which if not taken into consideration, could just lead to wanting more and more right up to the end, and never having had a fulfilled life. Life really is about fulfillment, and it is important that each of us use every gift at our disposal to get that fulfillment.
