“Sometimes your best investments are the ones you don't make.”

Quoted in A Living Architecture : Frank Lloyd Wright and Taliesin Architects (2000) by John Rattenbury
Context: Human beings can be beautiful. If they are not beautiful it is entirely their own fault. It is what they do to themselves that makes them ugly. The longer I live the more beautiful life becomes. If you foolishly ignore beauty, you will soon find yourself without it. Your life will be impoverished. But if you invest in beauty, it will remain with you all the days of your life.

“You have to be a romantic to invest yourself, your money, and your time in cheese.”

“Withdraw into yourself, as far as you can. Associate with those who will make a better man of you. Welcome those whom you yourself can improve. The process is mutual; for men learn while they teach.”
Recede in te ipse quantum potes; cum his versare qui te meliorem facturi sunt, illos admitte quos tu potes facere meliores. Mutuo ista fiunt, et homines dum docent discunt.
