Sahil Bloom is an American investor and author who was born in Weston, Massachusetts, to David E. Bloom (a professor) and Lakshmi Reddy (an entrepreneur). Bloom studied at Stanford University on a baseball scholarship and graduated with a double major in sociology and economics. After experiencing a baseball injury, he gave up his dreams of becoming a professional player and instead continued his studies at Stanford, graduating with a master’s degree in public policy. Bloom then worked for a private investment firm and dedicated himself to his career until he realized that career aspirations alone were not enough to allow him to create a healthy, meaningful life that reflects the five different types of “wealth.” Bloom founded SRB Ventures and SRB Holdings to invest in startups and is the author of a weekly online newsletter titled “The Curiosity Chronicle.” He lives in the US with his wife Elizabeth and son Roman.

Dr. George Vaillant is a Harvard researcher whose long-term study on aging has revealed that positive social relationships are a key factor in life satisfaction and longevity. Bloom uses Vaillant’s research to support his own argument that tending to one’s relationships is the key to living a happy life.
