How I Trained My Intuition to Make Decisions Quickly — and Raised $70 Million "It was a powerful forum for me to discover my potential," Andrew Blackmon says.

I run a company of 400 people. It's only possible because of a decision I made soon after we launched — even though it had nothing to do with business: I decided to see a therapist.

I hadn't set out to be an entrepreneur; I was an English major in college, busy reading Dostoevsky and philosophy. Then I rented a tuxedo to get married, and it was an atrocious process. There must be a better way, I thought. My groomsman, Patrick Coyne (who had the same experience), agreed, and we cofounded The Black Tux in 2013 with the plan to rent well-fitting, high-quality suits and tuxes online — which turned out to be operationally complicated and immediately popular.
