Hitesh Porwal lost potential earnings of $8 billion by failing to capitalize on opportunities to create businesses that addressed his complaints about transportation and movie ticket booking in Mumbai. His first missed opportunity was Ola, the app-based cab company now valued at $7 billion, which arose from his frustration taking non-air conditioned taxis. His second was BookMyShow, worth $1 billion today, which came from his difficulty getting tickets for new movie releases. He now sees problems as opportunities for wealth creation rather than just things to complain about.
