description: "I hereby set three major rules⭐ Never short sell again,⭐ Never buy options pre-market,⭐ Never let a single stock position exceed 30%The past phase has been a test of character. Life is a constant journey of trial and error, experiencing all the ups and downs. I lost 100k due to the flawed investment concepts mentioned above. The amount isn't huge compared to the community, but the pain is real.Don't go against the major trend. If you're not bullish, just remove it from your watchlist. Why bet on a short? Trying to squeeze out every last penny carries the potential risk of losing all your principal.Don't speculate, don't speculate, don't speculate. Long-term thinking and value investing are the only truths.Thus, after painful reflection, the road ahead is long. I hope to put these into practice."
