In more generalized terms, OP what you need to do is called risk management analysis.

At your age, your parents typically do this for you but its never too early to start learning it. It applies to many aspects in life, in chess its called adversarial thinking, or prophylaxis.

To do this, basically, you start by having a goal, something you want to do or have done. Then you start by asking yourself what are the most likely risks or outcomes (what can happen), then you extend that to the uncommon but do happen risks, potentially the risks and the rare risks if the failure is particularly critical as well (i.e. safety-critical, or impacts your well-being).

Write them down, then determine what your requirements, dependencies, and what your points of failure are, how many points of failure do you have, is there a single point of failure where everything depends on a single thing, can that break?

Once you have it on paper, then reorganize to reduce, eliminate, mitigate, or remove those points of failure. Sometimes that means creating redundancy (more than two of a thing to combat a single point of failure) because that provides flexibility. Brittle systems break, flexible systems can cope or gracefully degrade if a leg of the system diagram is broken. This is called system resiliency in IT.

Unexpected things will happen, and if you've gamed out what those outcomes are ahead of time, and worked backwards, and have a plan for dealing with them (mitigating), or have removed the issue by investing more or doing something differently, you are well on your way because you prepared ahead of time, and if something does happen you don't have to deal with the emotional shock alongside trying to figure out what you are going to do because you've written your plan out (step-by-step) and have contingencies in place. You just need to pull out the instructions you made, and follow them, and hopefully you've written the instructions, and validated them ahead of time.

They should be written in a way that you can mindlessly follow them because you won't be nearly productive while you are in it, strong emotions have a way of clouding our thinking and sapping our productive efforts.

When you first start doing this, it takes practice, which is why I said write it out, it can be as simple as a series of circle nodes as long as you account for those previous items how you write it out doesn't matter.

This is used in many different places, and its particularly critical in IT (i.e. backups, business continuity, disaster recovery). Contingency planning (another name for a part of this), means you always have at least one fallback plan. If its not written/documented, its not a plan.
