This was a fantastic interview, though not necessarily for the actual “how I built this” story. Reffkin had a winding path to achieve his success - he comes from a mixed race background, his father was a drug addict, and through his early adulthood he really didn’t know what he wanted to do with his life. His success through struggle was inspiring.
He mentions a very prescient piece of advice received from a mentor: Stop trying to make your weaknesses into strengths.
I love this idea. Focus on playing games where your strengths are amplified and your weaknesses are muted. Always endeavor to play the right games.
