My opinion with the TED the first secret of design

Fadell says that “normal" is human nature instincts，sometimes it makes our life more convenient. Then he cites a example of driving. But "normal" also let us turn a blind eye, let us thought the world was that way. He makes an example of the sticker on the fruit to prove that.Fadell opens the packaging of electronic products every time，he could found a box article always adhere to the little pieces of paper, "please charge before use."

So Fadell believes that first secret of design is "used against this nature instincts" . He gave three Suggestions for the audience.

Firstly, we need to look broader. Sometimes,we  see farther, sometimes we see a few steps back or use the existing experiment with different people.And we think what changes we can make.

Secondly, we need to look closer. We can get back there to feel that frustration and see those little details.

Finally, we need to think younger.We can think with the perspective of the young people, their eyes haven't form practice.
