Why time is your most important asset

Because it is not renewable.

Time is the only thing we have a limited amount of.  Sure, we might have limited money, but if we have time and health, we can earn more of it.

Health is the second most important asset.  If you are out of time, you have no health.  But you can be unhealthy and have time.  Ideally we would like to have both health and time.

How do you use your time?
