Don't buy society’s definition of success. Because it’s not working for anyone. It’s not working for women, it's not working for men, it's not working for polar bears, it's not working for the cicadas that are apparently about to emerge and swarm us. It’s only truly working for those who make pharmaceuticals for stress, sleeplessness and high blood pressure.
