Lesson Learned: Polymarket and the Danger of Emotional Overcommitment

My biggest mistake on Polymarket, and it cost me a good chunk of change on a $SPX related event, was letting my initial conviction morph into emotional overcommitment. I had a solid thesis for a 'NO' outcome, but as the price moved against me, instead of re-evaluating the probabilities objectively, I doubled down aggressively, convinced the market was 'wrong'. This wasn't hedging; it was pure revenge trading, trying to force my initial read to be correct, and I ended up significantly over-allocating to a position that ultimately resolved the other way. The lesson, clear as day, is to stick to your original sizing plan or re-evaluate with a completely fresh perspective, not out of a need to 'be right'.
