What's the one trade that permanently rewired your brain?

Been thinking about this all week instead of doing literally anything productive. Every single one of us has that one trade. Not necessarily the biggest win or the worst loss, but the one that fundamentally changed the wiring in your little skull forever. The one where afterward you were just a different animal. For me it was early on. I had actual real money, the kind you're supposed to keep in something boring, and I turned it into a pile of weekly calls because a green candle told me to. And for about two glorious days I was a genius. I was already mentally spending it. I was picturing myself explaining to normal people at parties that yeah, I just kind of have a knack for this. Diamond hands, baby. I could do no wrong. You already know how this ends. It didn't just go to zero, it went to zero in the most humiliating, drawn-out way possible, like the market wanted me to feel every second of it. And here's the thing that actually broke me. It wasn't the loss. It was that I sat there and watched it happen and did nothing, because some voice in my head kept whispering that it was gonna bounce back any second now. That voice has never once been right and I keep listening to it anyway. Ever since then I don't trade the same. I'm not saying I got smart, God no, I'm still here aren't I. But something shifted. Now every time I'm about to size up way too big I get this little flashback and my hands start sweating and I hear that same stupid voice going "it's different this time." Sometimes I listen. Sometimes I don't. The scar tissue is real either way. The weird part is I think that one trade taught me more than any book or any DD anyone's ever posted here. You can read about risk all you want but nothing hits like watching your own money evaporate in real time while you refresh the app like it's gonna change something. So I gotta know. What was yours? The trade that broke your brain, made you swear off options forever for approximately nine hours, or somehow turned you into the unbothered diamond-handed lunatic you are today. Win or loss, I don't care, I just wanna hear the story that made you who you are.
