I heard a story of a man who set up two fishbowls and filled one with a marble for every week he has left to live. At the end of each week, if he did something that he felt was worth something, he took one marble out of one fish bowl and put it in the other. If he didn't do anything of value, he threw the marble away. That's a pretty stark reminder. You actually have to throw the marble away - a week wasted. A week you'll never get back. The standard of what constitutes doing something of value is your own. It's a feeling. Maybe it's helping your kid with their homework. Maybe it's helping someone across the street. Maybe it's quitting the job you hate to go do something you love. Or maybe it's just sharing an idea that will inspire others to love every week they have left.
