Former reckless bikers, what was a wakeup call that you needed to stop your behavior

I'll go first when I was 15 I'd bike recklessly to school looking both ways? No, fuck that. I just drove like in idiot basically not giving a damn. It wasn't until one of the teacher talked about it. Looking back I realized how that might've been important considering the fact I knew better. I did it becuz my brain would always tell me "Don't be a pussy and cross the damn road." So yeah don't always listen to what ur mind says.
