I think the article oversees an important factor in startup success: the needs of the market is a vast land, and surely there is an intersection with a passion yours. I can’t envision the founder of Bang & Olufsen being indifferent to sound quality, or the founder of Herman Miller being indifferent to office furniture. I chose these companies deliberately because I don’t know their founders, but I’m sure they were passionate about their field.

I can’t fathom building a company for a market that might be lucrative, but is meaningless to me. I’d rather build 10 failed companies than create a profitable CRM for telemarketers.
