The temptation for convenience prevents many people from discovering what it is they like to make.

It is cited from The myths of innovation by Scott Berkun (O'Reilly, 2007).
I would recommend this book to anybody who's ever asked himself a question, 'Why people average people are so dumb? Why aren't they interested in so many interesting things that are around us?'
'Humans don't always like to know things.' (Uwe Bergmann, youtube video)

I also came upon a video of a Scott Berkun's lecture, his blog, a
the book on O'Reilly, and a 74-minute conversation in mp3. But I have not watched/listened to them yet. There's a lot of other multimedia on Scott's personal website.
