This oft-quoted statement comes from “The Notebook of Elbert Hubbard,” a collection of musings, short essays, and nuggets of wisdom from the eponymous writer, artist, and socialist philosopher that was published in 1927. The quote stands alone in the text, apart from any paragraph — a single thought about the fuel for our loftiest goals. What some may describe as zeal, spirit, or resolve, Hubbard names in his own way. For each step toward a mountain-sized dream, enthusiasm is what gives us the energy to push forward.
