Ah, yes, the thrilling process of untangling and rearranging code like a game of digital Jenga. And let's not forget how mobile app development moves faster than a cheetah on roller skates! It's definitely not as glamorous as it seems, but hey, at least you have "fun" written all over your exhausted face. Just remember: Keep calm and refactor on! 💻🚧
