Chris Hadfield2013First Canadian to command the ISS
The calmest person in a crisis is usually the one who has already rehearsed it. Hadfield's case for preparation over bravery.
Preparation, not bravery
Hadfield decided at nine, watching the 1969 moon landing on television, that he would become an astronaut, at a time when Canada did not have any. He then spent most of his career on the ground training for flights that might never come: a 1995 Shuttle mission to the Russian station Mir, a 2001 flight on which he became the first Canadian to walk in space, and a five-month stay on the International Space Station that he finished as its commander.
The book is less about space than about how that training rewires a person. Astronauts rehearse fires, leaks and even a crewmate's death until each one is familiar. Hadfield calls it the power of negative thinking: picture the failure in detail, and you find the action that prevents it or the first move that contains it.
Chris Hadfield spent most of a long career training on the ground for three spaceflights, and he argues that the habits that kept him alive in orbit work just as well on Earth. Rehearse what could go wrong, sweat the small details, and walk into a new team aiming to do no harm before trying to shine. The book makes preparation, not bravery, the source of calm under pressure.
Not dread: a running list of what could go wrong in the next minute, hour or day.
A short list you can act on beats a long list you can only worry about.
Run the sim until the emergency is boring. Familiar trouble does not cause panic.
The switch, the checklist line, the spare battery. Details are where disasters start.
Every run, real or simulated, feeds the next list.
The zero scale
Walking into a new team, you will be seen as one of three things. Most people try to prove they are a plus one on day one, and that is how they end up a minus one. Be competent, be useful in small ways, learn how things are done. The plus comes later, and others decide it.
Interactive · The sim room
Pick something coming up. List what could go wrong, rate how likely and how bad, and write a first response for each. Then run the sim: alarms fire at random, weighted by risk, and you have eight seconds to pick your procedure. The gaps show up fast.
Readiness is the share of total risk that has a written first response.
Your board, failures and procedures as a PNG to keep on your phone.
A plain-text list, sorted by risk, to print or paste into notes.

The question, as a loop
Partway through his first spacewalk, Hadfield's left eye suddenly stung shut. In weightlessness tears do not fall, so the liquid spread across to the other eye and he was, for a while, blind outside the station. He did not panic. He told the ground, worked through the problem with them, and the walk went on. Nobody had trained him for that exact failure, but years of drills had trained his response to failures he could not predict.

The book's ideas, ranked by readers. Vote for the ones you would put in your own procedures.
Hadfield trained for far more emergencies than he ever met, so the problems that did come felt familiar. Pick one event coming up this month and walk through what could go wrong before it happens.
For an astronaut the question is not anxiety but a way to keep a short list of what to do next. Ask a gentler version before a trip, a launch or a hard conversation, and fear turns into a set of tasks.
A misread switch or a skipped checklist line can matter more than any grand strategy. Choose the two or three details that would hurt most if missed and check them on purpose.
Hadfield sorts newcomers into minus ones, who create work and harm, zeros, who are competent and neutral, and plus ones, who add value. Rushing to prove you are a plus one is the quickest way to end up a minus one, so learn the place first.
Picturing failure in detail is how you find the actions that prevent it. The point is not to dwell on the worst case but to leave each one with a first response written down.
Hadfield spent far more of his career on Earth than in orbit, with no promise he would ever fly. If only the summit counts, most of your life becomes a waiting room; find what is good in the training itself.
Pilots use attitude for an aircraft's orientation. Deciding where you are pointed, and correcting it often, matters more than any single burst of effort.
On a long mission everyone depends on each person doing the dull jobs well and helping without being asked. Small acts of support build the trust that a crisis will draw on.
Checklists
List five ways your next big event could go wrong and write the first thing you would do for each.
Choose a recurring high-stakes task, such as travel or a presentation, and write its steps in order so you never rely on memory under stress.
Put what solves your three most common daily problems in one place: a charger, a spare key, printed directions, any medication.
Before joining a new team, write what competent and neutral looks like there: arriving prepared, listening, asking how things are done.
Walk through what your household does if the power fails or someone is hurt, and post the key numbers where everyone can find them.
Before the day starts, name the one thing most likely to derail it and your first move if it does.
Within a day, note what went well, what surprised you and one change for next time, without blame.
Once a week, spend fifteen minutes on something you need only now and then but must do well when it comes.
Rehearse the trouble, sweat the details, arrive as a zero. Calm is something you prepare.HourLife note after Chris Hadfield Back to the library
