Ever had a 'what if' moment that changed everything?

Senior year I had a big corporate internship lined up safe resume builder, all my friends jealous. Night before, got drunk with cousin and we drove to beach instead, missed interview completely. Met this random group there who became my best friends, got me freelance graphic work I actually love 6 years later. Parents were pissed at first but now they're proud. Could've been miserable suit life. What's your biggest 'screw the plan' moment? Did it work out or backfire hard? Would you do it again knowing what you know? Those split-second calls stick with you forever.
