Beautify this content using HTML tags, but without headers, footers, or images.
10 years of real-world troubleshooting: got it.
Focus on the point, start with a result.
Use short sentences when possible, break lines where needed.
Each point must be anchored with a real event, a time, or a number.
Directly say: This is a trap, don't believe it, don't do it this way.
Avoid: Definitional openings, theoretical phrases, symmetrical sentence structures.
End without summarizing, just a practical tip.
Example: - HTML
