I remember opening an old script file on our server for scheduled tasks, and thinking to myself; What idiot wrote this mess? It's unnecessarily complex, solving the problem in a convoluted way. And of course, not a single line of comments.

After reading it through and through many times to understand what each line did I kept repeating to myself; What an imbecile... Being this stupid should be illegal... Coding should require some sort of license to prevent idiots from doing this!

Then of course, it slowly dawned on me. I had written this crap one year before. I'm the idiot... 😐

I've commented every line religiously since then.
