A quote
But the mere place avails little for this purpose, unless the mind is fully master of itself, and can, at its pleasure, find seclusion even in the midst of business; the man, however, who is always selecting resorts and hunting for leisure, will find something to distract his mind in every place. Socrates is reported to have replied, when a certain person complained of having received no benefit from his travels: “It serves you right! You travelled in your own company!”
