The big takeaway is one of those rare things: It's not just a quick fix: it is a profound practice that creates instant results.
Here it is, the "Wonder Woman" power pose that everyone should do two minutes a day. And especially before any situation in which your work or who you are or how you present yourself is to be evaluated by others. You'll walk in feeling confident, powerful, the master of your world.
But how about those times when it's your own inner critic that does the evaluating? I've been doing the Wonder Woman pose before sitting down to work on my novel, and I'm happy to report that it's very effective.
I'm thinking of trying the costume as well.
