Florence once said something in an interview that changed how I thought about my own work. I've never forgotten it.
Their story
Florence Nightingale transformed nursing during the Crimean War and afterwards, using statistics and her famous rose diagrams to force reforms in hospital sanitation. The Nightingale School she founded in 1860 was the first secular nursing school in the world.
In their own words
“I attribute my success to this: I never gave or took any excuse.”

Beautifully said.
