What is Thoreau's remedy for our hectic, detail-crowded lives?

In terms
of the question, I think that Thoreau's answer would be to find solitude and revel in it.  For
Thoreau, the notion of solitude allows individuals to gain control over their own lives. 
Thoreau believed that social conformity and the notion of living life for others in the
cosmopolitan and social setting is one where individuals lose sight of their own lives.  In the
establishment of solitude, Thoreau feels that individuals can follow their own
"drummer" and live life on their own terms, finding their own voice in the process. 
It is this empowerment that helps to place the hectic details of consciousness in their own
perspective.  When Thoreau says, "To be in company, even with the best, is soon wearisome
anddissipating," he is suggesting that the best way to simplify consciousness into a unity
of pure and true is to find and establish a zone of solitude that is not to be permeated by
others and the trappings of society.
