Disagree, soft steel dents fast and teaches bad habits.

Did you ever think a single print line would teach you more than a whole semester of lectures? Honestly I used to roll my eyes at people who said that, figured they were just bad at reading code. Then I spent a whole night on a Java assignment where my array kept printing garbage, and one System.out.println inside the loop showed me I was resetting my counter every time. Two seconds of printing beat three hours of staring and guessing. That tiny habit changed how I debug everything now, I just ask the code what it's doing instead of assuming.

Oh man, I learned the hard way that a 6-inch taping knife is way faster for that.
