Rory Sutherland : Life lessons from an ad man

Rory Sutherland at TEDGlobal 2009  (transcript)
Life lessons from an ad man
Summary
This story seemed to be told about 10 years ago. Thus the meanings and effects of advertising must be quite changing because a lot of people become smartphone users more than before.

However, l don't think that our world becomes a place the speaker tells us where people know about intangible values well. Just many things are spreading but it's too many and too much thus people can't choose all the things but they can't think many things by themselves.

Ironically, a person who can change his/her perception must be a person who doesn't watch advertisements. We have to know that there's something that we can't see can change human behavior.
There are many funny advertisements, though, those confuse us. I think that this is the life lesson from him who is an ad man.
