@diane_xy writes about @amyjccuddy's TED talk:

A few weeks ago, I watched Amy Cuddy’s inspiring TED talk for the first time. If you haven’t seen it before, you should go watch it now. (Go on! I’ll wait for you to come back.)

In case you didn’t take my advice, here’s a basic synopsis: the talk explains the implications of Cuddy’s most famous study, which reveals an unexpected relationship between the way you carry yourself and the way you feel. Contrary to conventional wisdom, the relationship is not a simple one-way street. Rather, it is a feedback loop. Not only do your emotions affect your body language, but your body language also affects your emotions.

Diane's whole article on body language affecting emotions is worth reading:

Amy Cuddy's TED Talk: Your body language affects who you are.

Change your posture and you change who you are:

Body language affects how others see us, but it may also change how we see ourselves. Social psychologist Amy Cuddy shows how “power posing” -- standing in a posture of confidence, even when we don’t feel confident -- can affect testosterone and cortisol levels in the brain, and might even have an impact on our chances for success.

Amy Cuddy’s research on body language reveals that we can change other people’s perceptions — and even our own body chemistry — simply by changing body positions.

A comment on that TED page:

There are couple good blog posts from the Harvard Business Review that Amy Cuddy wrote that are short and on similar subjects. She is an associate professor of of business administration at the Harvard Business School.

But if you want to read something really compelling by her (and two other co-authors) try this article, 'Connect, Then Lead' on how to lead people and if it is better to be loved or feared: http://hbr.org/2013/07/connect-then-lead/ar/1

Then we need to go into the real world regularly and apply what we've learned.

There's a whole world outside the computer...

Online, offline, schmoffline...it's all the same: we either feel or we don't... and we either feel the feeling we want when we want to feel it for as long and as deep as we want, or you don't.

With practice feeling any spectrum of feelings can become an intentional, conscious choice.  Any and all artifacts we ascribe our feelings to are fungible, so we can pick what works for each of us and then practice feeling.  Or not.

Hey, so what are we choosing to feel today?

I'm choosing to feel good. You're right, that's a choice.

Hopefully.
