Missed out on a six-figure trade because I wasn't fully locked in when the opportunity hit. Still kicking myself over the $lumen play too—totally botched the execution. These are the moments that sting the most, not because of the money, but because you know exactly where you went wrong. Sometimes it's discipline, sometimes it's hesitation, sometimes it's just bad timing on your part. Either way, it's a hard lesson in staying sharp and committed when the market presents chances like that.
