Kat Cole started helping out early. Raised by a single mother of three who held three jobs to support the family, Cole entered the workforce as soon as it was legal. At 15, she started selling clothes at a mall. At 17, she added a second job at a restaurant—first as a hostess and then as a waitress. After juggling these jobs through high school, Cole became the first person in her family to attend college. She studied engineering and planned to go to law school, but those aspirations would soon be shattered. via How to Succeed Professionally by Helping Others – Adam Grant – The Atlantic.
