Think of Grandma Moses who began painting in her 70s,
Laura Ingalls Wilder who published her first Little House at 65
"Colonel Sanders" who didn't become a fried chicken mogul until his 60s
It's interesting that life changes prompted them all toward new ventures
Learn to draw or paint, or capture the world through photography
Take up a musical instrument
Write that novel you've had churning inside all these years
Build, stitch, carve, cook, blog...
The possibilities are limited only by your imagination
