Hello @chbartist!
Understanding the limited of our life time should be enough for everyone to value their lives and enjoy appreciating the small details of life. That is one of the things that shows us the wisdom of God.
Unfortunately, most people do not stop to think about what they are doing with their lives, without thinking that time never recovers, and that at some point these people will be 80 years old and probably will not even be able to walk alone.
This is the time to do everything we have always wanted to do, and use our creativity and talents to achieve all those things we want.
