I just read iLounge’s overview of an interview that Steve Jobs’ did with Fortune and I really liked this snippet:

After an extended period of living with the originally designed enclosure for the iPhone, Jobs concluded that he didn’t “love” the shell, an emotion that he would need to feel for what he believed was the company’s most important release ever. “[W]e pushed the reset button. We went through all of the zillions of models we’d made and ideas we’d had.” And, with too little time remaining before the device’s announcement, he challenged the designers to do better, quickly. “It was hell because we had to go to the team and say, ‘All this work you’ve [done] for the last year, we’re going to have to throw it away and start over, and we’re going to have to work twice as hard now because we don’t have enough time.’ “

Now that take guts (what Jobs did)… and hard work (what his team had to do).
