Read the excerpt from walden. i left the woods for as good a reason as i went there. perhaps it seemed to me that i had several more lives to live, and could not spare any more time for that one. it is remarkable how easily and insensibly we fall into a particular route, and make a beaten track for ourselves. i had not lived there a week before my feet wore a path from my door to the pondside; and though it is five or six years since i trod it, it is still quite distinct. what is the metaphor being used in this passage? lives to live door beaten track pondside
