This isn’t meant to belittle or scoff at people’s lived experiences, but the difference between “if I get this wrong, my company will lose millions of dollars” and “if I get this wrong, hundreds of people die” is VAST.
Communication is a learned skill.
Ability to handle stress and thrive under pressure is the key.
