I love this.
The average person lives about seventy-five years. I know, some live more and some live less, but on average, people live about seventy-five years. If you multiply 75 times 52, you get 3,900, which is the number of Saturdays that you may get in your entire lifetime. How many of yours have already passed?
The marble jar:... Get a jar. Put a marble in it for each Saturday you have left. As every Saturday passes, take one marble out and throw it away. Watch the marbles diminish as a reminder that you should focus on what you want to do, what you want to have, and who and HOW you want to be – what YOU decide is really important in life.
