Comments Are Very Important

The gradual descent into madness every developer experiences when they convince themselves comments are unnecessary. "I'll remember what this code does" is the battle cry of the optimistic junior, while the clown makeup represents the inevitable reality check six months later when you're staring at your own hieroglyphics wondering what dark magic you were attempting to summon.

Future You will absolutely hate Past You for this decision. The final form—full clown regalia—is what you deserve when you realize the code that "only you will work on" is now being assigned to the new hire who keeps asking why there's a function called fixThisLater() with zero explanation.
