Liz Smith(1921-2016)

Did not work professionally as an actress until age 50, from which point she became one of the most recognizable faces on television and film and was named as the nation's favorite fictional grandmother. Before that she had lived a difficult existence of relative poverty, working in dead-end jobs while raising two children on her own.

My advice is: Never peel potatoes. Think of the time that would be saved in this country if nobody peeled potatoes.
