Edward Hopper was an American realist painter who gained notoriety around the early part of the twentieth century, however, Hopper was a bit of a miserable fellow.
By age 40, Hopper was essentially a failed painter. Nobody liked his stuff and it wasn’t selling. Hopper never stopped and eventually, his best-known works, Nighthawks, House by the Railroad, Automat, and more became hits, and Hopper by about age 42 was much more successful.
So if you think you’re a failure at age 22, or 32, or even 42, stop. There is so much more time and potential. Heck, who says you can’t start a business at 72 years old and run that for two (or three!) decades?
