I Will Use It Later I Promise

You know that variable you declared with such confidence, thinking "I'll definitely need this in a few lines"? Yeah, it's been sitting there for three months now, collecting dust while your IDE passive-aggressively underlines it in gray. The variable just wanted to be useful, to hold some data, maybe participate in a calculation or two. Instead, it's stuck in declaration limbo, watching all the other variables get to do cool stuff while it just... exists. And the worst part? You're too attached to delete it because "what if I need it later?" Spoiler: you won't. But you'll keep it anyway, like that gym membership you swore you'd use.
