The '20s ended in an era of extravagance, sort of like the one we're in now. There was a big crash, but then the country picked itself up again, and we had some great years. Those were the days when American believed in itself. I was happy and proud to be painting it. Norman Rockwell
My parents survived the Great Depression and brought me up to live within my means, save some for tomorrow, share and don't be greedy, work hard for the necessities in life knowing that money does not make you better or more important than anyone else. So, extravagance has been bred out of my DNA. David Suzuki
