Yasmeen Lari was a famous Pakistani architect celebrated for her work in steel, cement, and glass. In her 60s, she turned her back on all that, and, after a massive earthquake hit her country, she began to work with locals building humble homes of adobe, mud, and bamboo. Painter Henri Matisse, when debilitated by stomach cancer in his 70s, hung up his brushes and took up scissors to continue making art. And, the Disney illustrator Tyrus Wong waited until he was 90 years old to receive full credit for the revolutionary work he'd done on "Bambi." Never say it's too late to succeed!
