Glory as a gardener is all about the small things. Clients want gardeners to basically be glorified lawnmowers, so you'll have to take pride in doing the best job you can with that lawnmower. It'll be difficult to stand out—uniforms are often colored drab green to blend in as much as possible with the surrounding landscapes—so you'll have to get noticed by making the property gloriously beautiful.
Even the dog poop that you'll have to clean up will just be—you know what? Never mind. There's really nothing glorious about cleaning up dog poop.
