Steve Jobs once chucked an iPhone prototype to impress a room full of journalists.

I kind of love this concept. Not because it’s the kind of gambit he might pull, but because it illustrates the point so perfectly. Unscathed or smashed beyond all recognition anyone’s question about the device’s durability would have been reasonably answered beyond all doubt.
Plus there’s another point: not to be afraid of trying. I’m sure some engineer somewhere had quite the puckered ass at the time. But you can’t be held back by fear if you want to accomplish something meaningful.
