"The happiest destiny on earth is undoubtedly to have a distinguished and rich individuality and in particular a good endowment of intellect. ... Whoever has been granted this lot through the favour of nature and fate will be anxious and careful to see that the inner source of his happiness remains accessible to him and for this the conditions are independence and leisure. And so he will gladly purchase these at the price of moderation and thrift, the more so as he is not, like others, dependent on external sources of pleasure. Thus he will not be led by the prospects of office, money, favour, and approbation of the world into surrendering himself in order to conform to the sordid designs or bad taste of people."
