When I read Walter Isaacson's biography of Steve Jobs, I was blown away with the story of the NeXT computer after Jobs left Apple inn 1985. (an amazing book, by the way) He hired the graphic designer, Paul Rand, to create the logo. In addition to the logo, he told Steve Jobs he would design a new business card for him while he was at it. "Steven P. Jobs, President"
The two nearly got into a fist fight over where the period goes after the P. Does it go after the P like a typewriter? or does it go under the loop of the capital P? (which was a new concept with typewritten computer displays) Rand wouldn't back down, and refused to make the card because of the period debacle, and Jobs ultimately had someone else design the card for him.
Most people roll their eyes when I tell this story... But me? I think this is the epitome of passion.
Let me ask you: Ever ask someone to change something, and they refuse? Why? Are they refusing because they care and will fight you to the death? ... Or are they refusing because they're busy, or don't fully understand what's going on in the first place? A lot of people just don't care, and they call this micro-management. Who are these people really serving? Their team? Their customers? Or themselves?
On the other hand, what if you built something marvelous, and brought this kind of passion for detail to every single aspect of what you're building? First of all, you would need people who care just as much as you, and not just going through the motions. Do you think that would have a positive or a negative effect on the outcome?
