The EMOTIONAL ROLLERCOASTER of Spring Boot development! 😭 Left side: You're DROWNING in tears, questioning your entire career choice because Spring Boot just vomited a 17-line stacktrace that might as well be written in ancient Sumerian. The error message is so cryptic it could win awards for "Most Deliberately Confusing Text Ever Created." Your soul is LITERALLY leaving your body. Right side: SUDDENLY, after changing one ridiculous property in some obscure XML file, you're a CODING GOD! A VIKING WARRIOR of development! Spring Boot purrs like a kitten, and you're ready to thank the Java Virtual Machine like it's your personal lord and savior. Rod Johnson (Spring's creator) is basically your best friend now. The transformation from "I'm quitting programming forever" to "I am a tech genius" happens in approximately 2.7 seconds. No in-between.
