I originally saw this on a Tony Robbins pod.
"Tiny tweaks can lead to big changes. So, this is two minutes. Two minutes, two minutes, two minutes. Before you go into the next stressful evaluative situation, for two minutes, try doing this, in the elevator, in a bathroom stall, at your desk behind closed doors. That’s what you want to do. Configure your brain to cope the best in that situation. Get your testosterone up. Get your cortisol down. Don’t leave that situation feeling like, oh, I didn’t show them who I am. Leave that situation feeling like, I really feel like I got to say who I am and show who I am."
