Scuffs and dents are just one obvious kind of mark. Every comment you make to somebody also leaves a mark. It’s unlikely, perhaps impossible, that it would have exactly zero effect on the rest of that person’s life, and so we must assume that they are, to some degree, forever changed.
We’ve left a path of lasting evidence throughout our whole lives. In fact, that’s really all our lives are: the impressions we’ve left, the moments we’ve created, the marks we’ve made. Once you’re dead and gone, the work you did is still done. The things you built still stand, or maybe lean or lie in rubble, but they won’t go away. The people who knew you still know you, and still operate under your influence, whether they know it or not.
Every second you exist, you’re scattering a broad trail of signatures on who knows what, laying causes to an untold ocean of effects that will carry on far beyond your death. The person who invented paper is certainly dead. Did his life affect yours today?
The founders of your city, of your religion, of your language, are all probably dead too, to say nothing of your great grandparents, or theirs. What if they had done something different with their time?
Each action you take creates a resounding shock wave that never entirely dissipates. Even in the grand scope of the whole planet, it matters. You matter, much more than you probably think.
You’re not a drop in the bucket, quite the opposite. In a very real way, the world will be profoundly and permanently changed as a result of what you do while you’re here. It can’t be helped.
That’s a lot of responsibility. What are you going to do with it?
