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.
