One of the easiest ways to massively speed up your debugging (and make yourself look way more senior) is simple: write things down early and often. Here are the core points from the lesson:
Don’t wait for clarity to write—writing your thoughts down is what creates clarity and uncovers next steps
Always document repro steps, failed attempts, blast radius info, and hypotheses while debugging
Writing things down improves your retention, narrows the search area, gives credit to others, and makes handing off bugs much smoother
Even half-baked notes are powerful because they build momentum, reduce confusion, and help you communicate progress to others effectively
