Harry Stebbins had a great interview with venture capitalist Michael Dearing on the 20 Minute VC Podcast a couple weeks ago. Michael talked about a trait that he looks for in founders and startup teams that he refers to as "personal exceptionalism". This is the idea that a person believes that they are special and that their outcomes are going to be "outside the bounds of normal". They’re not arrogant, they just strongly believe that they can produce results far greater than the mean.
This idea really resonated with me; not as an investor but as a person that hires a lot of people and builds teams and is constantly trying to scour through candidates to find the best of the best. The notion of personal exceptionalism really captures what I look for. Rather than try to explain the concept myself I've transcribed Michael's comments on it below. Spot on.
