I find that, particularly with geek stuff, I get hung up on tiny little details. For example, I did a deep dive with Javascript and CSS the other week, trying to find out why I couldn’t get an input field to select all the text inside when I clicked on it. This ties back to Spolsky’s thoughts on craftsmanship.
But if I channel Godin for just a bit, I’d remember that the whole product is important- not just one tiny detail. It’s fine to care about little details once the building is built, but while you’re building- keep going.
