That’s a superpower. Your mind is able to be stable and calm and focused against almost any force, any challenge, any problem. Your brain is like the large jets most people fly in, which are built for insanely greater stress, power, and force than most of us will ever experience on any flight. You can thank your ancient ancestors for that. They lived and died in unimaginably horrible conditions, building and fighting and hunting and reproducing in the barren deserts and frozen mountains, terrified of the night and striving with their last ounce of strength to stave off the moment when hunger, thirst, disease or predators would inevitably snuff out their precarious existence. Their great suffering and effort over millions of years hammered and welded into shape a thinking machine that is extraordinarily smart, and tough, and resilient, and which is uniquely complex and powerful in the entire universe we know.
