Here are the things I have always kept in mind in continually working to evolve the companies I've run.
There is a long simmering, rather interesting argument around the notion of "nurture vs. nature" as it relates to human beings and their abilities. The Eddie Murphy film Trading Places was actually based on it, with a bet revolving around whether he could learn the commodities business without being born a blue blood.
I’m often asked whether entrepreneurs are born or made, and I firmly believe that entrepreneurs are born. Why? Because the mark of a good entrepreneur is that you’re never satisfied, you’re not OK with the status quo and you’re out to change the world no matter how large or small. Even looking back to my youth, I was always the kid in school to ask “why?” and I’m sure that rings true for many of us.
Find the operational bottleneck.
Focus on your minimum viable product.
Never forget: You are not your customer.
