I can think of two good ways to leave your mark. One is to get a sharp edge like one found on a knife or even a rock. Next, find a tree, picnic bench or some wooden structure. Then just get busy carving.
Write something like Jim-N-Carol or Danny HEARTS Audrey. The results may last a hundred years depending on how long it takes the termites to find the carved surface or for fire to reduce your work to ashes.
Another way to leave your mark is to develop another person, maybe an employee or a child. If you choose well whom you develop, your mark may last indefinitely, beyond several lifetimes.
You’re going to leave a mark. What kind you leave is up to you.
