Never search for the same fix twice
Note what actually worked, right on the Stack Overflow answer, GitHub issue, or doc page where you found it.
So the same search doesn't happen twice
The thirty minutes you spent finding it, spent once
Keep the answer that worked
Note the Stack Overflow answer that actually worked and why, so you don't reread the whole thread next time.
The conclusion of what you read
Leave a line or two of what an article concluded. A bookmarked title won't remind you of the content.
Decisions made in the thread
Record why a PR or issue went the way it did, so the discussion doesn't restart from scratch later.
The parts of the docs you keep returning to
Note the options and signatures you look up every time and build your own reference.
