Adopting the right attitude can convert a negative stress into a positive one. – Hans Selye
Stress releases cortisol, a toxin that clouds your thinking.
Stress shuts down your systems, including your rational thinking.
Which is why, Daniel said you need to have a system in place.
A system that is planned way ahead of time, pre-mortem, as he would call it. A system that says, you would do this if that would happen. It leaves the decision making process out.
Knowing that you are flawed, we are human after all, when things happen. Our rational thinking would be thrown out of the window.
What happens then? What systems do you put in place? To ensure that you making the best decision in that situation?
