Sitting quietly

> I have often said that the sole cause of man’s unhappiness is that he does not know how to stay quietly in his own room. A man wealthy enough for life’s needs would never leave home to go to sea or besiege some fortress if he knew how to stay at home and enjoy it.
– Blaise Pascal, Pensees, VIII, 136

*Update*: apparently [sitting alone is so unpleasant that people would rather give themselves electric shocks](http://www.nature.com/news/we-dislike-being-alone-with-our-thoughts-1.15508).
