What’s the world going to do in your absence?
It depends on what did to you offer the world that no one else could.
What will the world miss about you?
It depends on how well you treated other people but also how well you combined intelligence and creativity. Maybe you made something that no else can seem to replicate. Maybe you just had unique taste that other people admired.
So much of your life’s value is based on love and effort. What you tried to show, to do, to be, whether or not you actually achieved it, depends on the honesty in which you pursued it.
Is there anything you still want to do?
You’re better off deciding right now what those regrets may be.
