THIS is an excerpt from therapist Laura Trice's speech at TED in 2008: Hi. I'm here to talk to you about the importance of praise, admiration and "thank you"s, and making them specific and genuine. The way I got interested in this was, I noticed that when I was growing up, and until about a few years ago, I would want to say thank you to someone. I would want to praise them. I would want to take in their praise of me and then I'd just stop myself. I asked myself: why? I felt shy. I felt embarrassed. And then my question became: am I the only one who does this?

So, I'm going to challenge all of you. I want you to true your wheels: be honest about the praise that you need to hear. What do you need to hear? Go home to your wife and ask her: "What do you need?" Go home to your husband and ask him what he needs. Go home and ask those questions and then help the people around you. It's simple. But why should we care about this? We talk about world peace. How can we have world peace with different cultures, different languages? I think it starts in each of our households. So, let's make things right in our own backyards. The purpose of the speech is most likely to   _  .
