You know that feeling when your code compiles on the first try? That's not victory—that's a red flag. After enough years in the trenches, you learn that code which works immediately is basically a ticking time bomb. No compiler errors? Congratulations, you've just written something so cursed that even the compiler is too scared to complain. It's sitting there, silently judging you, knowing full well you've got edge cases hiding like landmines and race conditions waiting to ruin your 3 AM on-call shift. The real pros know: if it compiles first try, you either forgot to save the file or you're about to discover a logic bug so subtle it'll haunt production for months. Trust nothing. Test everything. Especially the stuff that looks perfect.
