I am reading a book I love and it's not even about Civil War battle strategies for once

“People talk about confidence without ever bringing up hard work. That’s a mistake. I know I sound like some dour older spinster on Downton Abbey who has never felt a man’s touch and whose heart has turned to stone, but I don’t understand how you could have self-confidence if you don’t do the work... I have never, ever, ever, met a high confident person and successful person who is not what a movie would call a 'workaholic.' Because confidence is like respect; you have to earn it.” 
― Mindy Kaling, Why Not Me?

This feels especially relevant for women.
