The radical part of Thoreau's advice isn't the dreaming—it's the *confidence*. Most people wait until they've secured permission, proof, or a guarantee before moving forward, which means their dreams stay perpetually postponed. What Thoreau understood was that the confidence comes not before the journey but *through* it; you become bold by acting boldly. A person switching careers at forty-five, or starting a small business from a garage, rarely feels ready beforehand—they simply decide the imagined life matters more than the comfort of hesitation, and that decision itself becomes the engine.
