For some reason, when I was young, I felt that I had lots of time. Like every young person, I felt I was going to live forever and consequently whether I got something done today or tomorrow did not really matter. Now that I am older, all I feel is a sense of urgency. The amount of time I have left to do the things I want to do is getting less and less. There is a book with the title “4000 weeks”. As should be clear from the title, the point of the books is that a human with a normal life expectancy, around 80, has 4000 weeks in his or her life. The question is what you want to fill those weeks with. What is your purpose, in your work and in your life, that you feel makes for a good use of the biggest gift that any of us have received: existence. And to make matters worse, there are things that you will no longer be able to do when you’re in your 50s, 60s, 70s or 80s. So, for many things, ranging from bringing children into this world to running marathons, you have much less time than 4000 weeks. So, perhaps experiencing a sense of urgency is not a bad idea?  Or do you think we’ll beat death before it’s your turn?
