Original doesn’t have to be loud. A quiet idea done carefully can stop people just as hard.

Impact and volume are often confused. A small, precise thing done with obvious care stops people in a different way from something designed to shout, and the effect frequently lasts longer. Loud work competes for attention, quiet work rewards it. Both are legitimate, but one of them is available to you without any money or spectacle at all.

Make something deliberately small and finish it to a standard nobody asked for. A single page, one perfect minute, one object made properly. Put it somewhere people will encounter it quietly and watch what happens, which is usually more than you expect.
