Many people have credited their time in nature with inspiring creative ideas, problem solving and even movements:

Henry David Thoreau, the famous transcendentalist writer from the 1800s wrote his first book when he moved to Walden Pond for two years to experience a simpler life, and connect with nature. He would take daily walks in the woods, read and journal. He found greater happiness in living simply and mindfully in nature, in a rustic cabin than in modern society or “over-civilization.”
“Go confidently in the direction of your dreams. Live the life you’ve imagined.”

Ralph Waldo Emerson, the founder of the transcendentalist movement and American poet from the 19th century who championed abolition and wrote about the virtues of listening to your intuition
“To be yourself in a world in a world that is constantly trying to make you something else is the greatest accomplishment.”

John Muir founded the Sierra club in 1892 and had a big influence in the expansion of the national parks in the United States.
“In every walk with nature one receives far more than he seeks.”
