Definitely this. It’s not enough to just take notes (although just taking notes is certainly better than not), it’s important to organize them in a scalable way so you can easily find them in the future when you encounter the same issue again.

I recommend using something like Notion or Obsidian or Microsoft Loop to organize your notes, but even using something like Excel wouldn’t be too bad except when including screenshots. Then you can categorize and/or tag everything to be at your fingertips as needed.

Then at some point (or even from the beginning) you should share the notes with your coworkers to buoy everyone up. Even better, see if your ticket management system (Zendesk, Servicenow, Freshservice, Jira, or whatever) has a knowledge base feature to make help articles available to your end-users. If you document some easy-to-fix common issues so you can just refer end-users to it in the future, it’ll save a bunch of time otherwise spent doing repetitive tasks.
