The Debugging Technique That Saved Me 100 Hours This Year

Look, I used to be the kind of developer who would stare at broken code for 45 minutes straight, convinced I could just think my way to the answer. Spoiler: I couldn't. And neither can you. This year I finally got serious about debugging. Not "add a print statement and pray" serious. Actually serious. And it genuinely saved me around 100 hours. I tracked it. Here's everything I learned. The Real Cost of Bad Debugging Before we get into techniques, let me hit you with some math that changed how I think about this. The average developer spends 35-50% of their time debugging. That's not my number, that's from a Cambridge University study. If you work 40 hours a week, you're spending 14-20 hours just finding and fixing bugs. Now imagine you could cut that by even 30%. That's 4-6 hours back every single week. Over a year? That's 200-300 hours. Enough time to build a side project, learn a new language, or just... not burn out. The techniques below helped me cut my debugging time by roughly h
