A navigator plotting a course does not spend the whole voyage imagining the smooth water ahead. Before setting out, they chart the rocks. Not because they expect to hit every one of them — but because knowing where they are is what allows confident sailing. The chart is not pessimism. It is preparation organized as information, and the result of doing it is that you can move freely within the space the rocks define.
Chris Hadfield, the Canadian astronaut who commanded the International Space Station, has a name for this approach as it applies to life inside one of the most unforgiving environments humans have ever occupied. He calls it the power of negative thinking. In An Astronaut’s Guide to Life on Earth, he describes it this way:
“Like most astronauts, I’m pretty sure that I can deal with what life throws at me because I’ve thought about what to do if things go wrong, as well as right. That’s the power of negative thinking.”
The concept runs against a fair amount of popular advice. The self-improvement genre has long favored visualization of success — picturing the outcome you want as a way of building the belief that will carry you toward it.
Hadfield’s argument is not that optimism is wrong but that confidence built on visualized victory is fragile. It has not been tested. It rests on the assumption that things will go as hoped. Confidence built on having thought through the failure modes, by contrast, has already survived something. It knows what it will do when a plan falls apart.
Negative thinking, in Hadfield’s sense, is not catastrophizing. It is not lying awake at night constructing elaborate worst-case scenarios and spiraling through them. The two can look similar from the outside — both involve thinking about things going wrong — but they tend to produce very different results. Where catastrophizing can function as a loop that amplifies worry rather than resolving it, Hadfield’s version is a structured practice: you identify the most plausible failures, you decide in advance what you would do about each one, and then you close the file and move forward, having earned the confidence rather than simply claimed it.
A quick note: If anxiety around failure is something you find genuinely difficult to manage, it is worth speaking to someone qualified to help — what follows is a productivity framing, not a clinical one.
In astronaut training, this process is formalized. Before any mission, crews work through failure scenarios exhaustively — which systems are most likely to malfunction, which emergencies require an immediate response, and what contingency procedures exist for each. The goal is not to produce fear but to produce readiness.
How to apply it to your own life
1. Start with the most plausible failures, not the most dramatic ones
The point is not to imagine every conceivable catastrophe but to think clearly about what is most likely to go wrong with the specific plan you are about to execute. For a business idea, that might be demand being lower than projected, or a key assumption proving incorrect before the timeline plays out. For a project at work, it might be a dependency that does not materialize, or a deadline that has not been properly negotiated with the people it affects. The useful exercise is identifying the two or three failures that are genuinely probable. The ones that would make the best disaster film can be set aside.
2. Write the answers down, even roughly
For each failure mode you identify, write down — even in a single line — what you would do if it happened. This matters more than it might seem. A contingency that exists only in your head stays available for anxiety to revisit. One that is written down has been answered. The act of putting it into words is what converts it from a source of vague dread into a closed loop. You do not need a full contingency plan for every branch. You need enough of a response that your mind accepts the question as resolved and stops returning to it.
3. Distinguish preparation from prophecy
Having identified that something could go wrong does not mean you are predicting that it will. This is the step that separates Hadfield’s approach from the pessimism it can superficially resemble. You are not telling yourself the plan will fail. You are telling yourself that if it does, you will not be caught without a response. The plan is still the plan. You are just carrying a map of the rocks along with it.
When I think back to the business ventures that did not work — an online school that ran out of money, a coffee startup I eventually walked away from — what I notice is not that I was too optimistic about them. It is that my version of optimism was mostly focused on what success would look like, and very little on what the failure points were and how I would respond to them. The first time something significant went wrong, I had to figure out my response in real time, under pressure, with no prior thinking to draw on. That is a worse position than the alternative.
The freelance writing path I eventually settled into has a different texture to it. I still do not do this perfectly. But I am more likely now to sit with a plan and ask where it is weakest before I start. Not to talk myself out of it — to make sure I know what I am getting into and have thought about what the exit looks like if the key assumption does not hold. It makes starting things slightly less romantic and considerably more considered.
Hadfield’s confidence, the kind he describes in the book, is not the confidence of someone who does not think much about failure. It is the confidence of someone who has thought about it more carefully than most people are comfortable doing. The rocks are on the chart. The sailing is genuine.
