If you’re really lucky, or extremely unlucky, you may realize how short your time is on this planet sometime in your teens. For most people, this revelation comes much later, but let’s be generous and use 15 years old as the starting point.
You get to see the leaves change color 60 times. If you’re lucky.
You get 60 Thanksgivings, Christmases, Fourth of Julys, and Easter egg hunts. If you’re lucky.
You might only get 45 chances to sing Happy Birthday to your kids or your parents. If you’re lucky.
No matter how busy you are, don’t squander those chances.
