John Zimmer is the cofounder and president of the ride-hailing service Lyft, which has faced a fierce competitor in Uber since the beginning. Lyft is valued at $7.5 billion, covers 94% of the US population, and one of its biggest advantages seems to be its "nice guy" reputation. But it can be hard for nice guys not to finish last. On this episode of "Success! How I Did It," Zimmer tells us how he got rich by not caring about money, plus how he survived early startup years by living on a friend's couch and eating frozen meals from Trader Joe's.
