The author and philanthropist Jennifer Risher continues our series on extreme wealth by telling the story of her ear-popping rise from a middle-class Microsoft employee in the early '90s to an unexpected multimillionaire. The stock options she accrued with her husband, David — a fellow Microsoft employee who went on to join Amazon and who is now the CEO of Lyft — gave Jennifer immediate entry to a world of privilege that, as the child of a working-class household, she'd never expected to join. Her experience showed her the peculiar nature of personal wealth: an agent of tremendous power that, she finds, does more to amplify people's character than to alter it.

Jennifer Risher is the author of "We Need to Talk: A Memoir About Wealth," which aims to illuminate discussions of money that are often cloaked in taboo, guilt, and secrecy. She and her husband founded the #HalfMyDAF movement, which seeks to encourage wealthy people to make greater charitable gifts in their lifetimes.
