Tiny tweaks can lead to big changes.

Don't fake it till you make it. Fake it till you become it.

Even more dramatic, Alex Todorov at Princeton has shown us that judgments of political candidates' faces in just one second predict 70 percent of U.S. Senate and gubernatorial race outcomes, and even, let's go digital, emoticons used well in online negotiations can lead to you claim more value from that negotiation. If you use them poorly, bad idea. Right? So when we think of nonverbals, we think of how we judge others, how they judge us and what the outcomes are. We tend to forget, though, the other audience that's influenced by our nonverbals, and that's ourselves.

I would say there is a conversation happening between your body and mind all the time. Even when you're sleeping, your body is communicating the information to your mind. And so to me it feels like, why not harness that? If it's happening all the time, why not control the content of the conversation?

Everyone is walking around with these self doubts, so there's something reassuring about that. And self-doubt in one or a few areas doesn't mean that you have generally low self-esteem. And you have the power to get yourself out of feeling that way.

Tiny tweaks can lead to big changes.

That's the dream scenario: when people approach these stressful situations not focused on that concrete outcome but just focused on being there and being themselves and enjoying connecting with people. You're not going to be present all the time, but if you can figure out how to connect with yourself and bring that self forth in those moments, you will probably be feeling a lot better over time, and it's likely that even though you're not focused on the outcome, the outcomes will be better.
