"Fear is core to our brain's biology. Yet for thousands of years, wise men have warned: Fear is irrational. Don't listen to it.
The wise men are wrong. Fear is smart. Very smart. It is sending you critical intel. That intel is: You have no plan.
There are different ways to arrive at no plan. Perhaps you had a plan, but it failed. Perhaps you ignored the need to make a plan, sticking your head in the sand. Perhaps you didn't know you needed a plan, and life surprised you. Perhaps you have a plan that looks great on paper but inspires no confidence in your brain.
It's critical to know that you have no plan, because a plan is the key to intelligent success. Without a plan, you have to be lucky. So fear is warning you: You have passed beyond the edge of your intelligence — and are about to become a captive of events!…
Why is fear the emotion that our brain evolved to signal this? Why out of all the signals that our biology could have evolved, did our brain develop an emotion that makes our knees weak and our minds blank?
The answer is: The brain has evolved a bias to action, because action is how we learn."
