Identify the things that make you feel powerless so you can have a lot more control over it
Pay attention to your body. Keep in mind when you go [into major presentation or public-speaking event], your body is sort of responding as if you're in a really threatening physical situation. Your body is going into fight-or-flight mode, and that's not adaptive to the actual circumstances that you're in [...] So first notice that your body is actually overreacting [...]
The second thing is to start paying attention to when your body language starts to collapse [...] Also, notice when those things happen [in your life] so you can identify your triggers [...] So much of the mind-body connection is about really understanding what your body does [...] if you feel that you're collapsing as you start speaking, you have to force yourself open [...] make sure that your body is staying open.
So open up your body, do not allow yourself to collapse [...] Even slow your speech because, if you get nervous, you will likely start speaking too quickly. And that makes you feel less powerful and it also makes you appear less powerful. And all of these things that you can do will not look strange to other people at all. In fact, they're going to signal to people that you're confident.

Every time I read a management or self-help book, I find myself saying, “That’s fine, but that wasn’t really the hard thing about the situation.” The hard thing isn’t setting a big, hairy, audacious goal. The hard thing is laying people off when you miss the big goal. The hard thing isn’t hiring great people. The hard thing is when those “great people” develop a sense of entitlement and start demanding unreasonable things. The hard thing isn’t setting up an organizational chart. The hard thing is getting people to communicate within the organization that you just designed. The hard thing isn’t dreaming big. The hard thing is waking up in the middle of the night in a cold sweat when the dream turns into a nightmare.
