Spent the last year building an AI tutor for developers, and the biggest pattern I've seen: most self-taught devs debug by guessing, not by reading.

Here's the loop that actually works, and it's the same one senior engineers use without thinking about it:

1. Read the error message top to bottom, not just the last line. The stack trace usually tells you exactly which function call broke and why — most people skip straight to Googling the last line and miss the actual cause two frames up.

1. Isolate before you fix. Comment out or log-check each piece until you know precisely which line produces the bad state. Don't change five things and hope one works — you'll never learn which one mattered.

1. Ask 'what did I expect vs. what happened' before you ask 'what's wrong.' This forces you to articulate the actual bug instead of pattern-matching to a Stack Overflow answer that doesn't apply to your code.

1. Write the fix, then explain it out loud (or to an AI) before you ship it. If you can't explain why it works, you didn't actually fix the bug — you got lucky.

This is exactly the loop we built into BrainBoost AI — it reads your actual code and error, walks you through this process instead of just handing you a copy-paste fix. If you're learning to code or leveling up in a new stack, it's built for exactly this moment of being stuck.
