You can replace things when they break or wear out.
You can always earn more money.
But you can't earn more time.
Or can you?
If you exercise 30 minutes a day you will most likely live a longer healthier life. The quality of your life will be better.
If you floss daily, you will live an average of 2 years longer. And the quality of the lives of people who talk to you will be better.
A positive attitude adds both quantity and quality of time to your life.
In the end - time is like money: If you make good use of what you have, you will receive more.
