Liz Smith(1921-2016)

Did not work professionally as an actress until the age of 50 and from that point, became one of the most recogniseable faces on television and film, being named as the nation's favourite fictional grandmother. Previous to acting, she lived a difficult life 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.
