There is also a secret truth in here about writing technical documentation, if you're looking for it

Sometimes, an item will be on my packing list, and I'll deliberately decide to not bring it because it's not relevant to the upcoming situation, and then it turns out it's also important in situations that aren't obvious from just looking at the list. Recent cases-in-point:

• Just because it's a temperature where I'd wear shorts on a run, doesn't mean it's not a temperature where I'd wear gloves.
• The re-used gelato jar we use for cold-soak lunches on the trail is also an important prep tool for certain dinners, and we might have one of those even if we don't have soakable lunches.
• That cold-weather neck buff also forms part of my camping pillow, by keeping my face from sticking to a nylon stuff-sack.

Whenever you Do This To Yourself, the trick is that you have to go back to your packing list and explain why you want to be sure to bring it next time. Your future self does not like following orders, and they're going to be uncooperative and chaotic unless you tell them what you were thinking.
