His house he lived in for over two years wasn't winter friendly. (Thoreau, 372) But he believed that spiritual well-being was more important than financial well-being. He didn't care about the cost, he just enjoyed the scenery and getting away from all the distractions that was happening in his life.
He says "Let us spend one day as deliberately as Nature, and not be thrown off the track by every nutshell and mosquito's wing that falls on the rails." (Thoreau, 375) This emphasizes living a simple life.
"I cut my way first through a foot of snow, and then a foot of ice, and open a window under my feet, where, kneeling to drink, I look down into the quiet parlor of the fishes..." (Thoreau, 376)
"I learned this, at least, by my experiment; that if one advances confidently in the direction of his dreams, and endeavors to live the life which he has imagined, he will meet with a success unexpected in common hours." (Thoreau, 378)
