Remember, you have not lost any money until you sell at a loss. So don't do that.
I'm not a fan of that mentality. Selling at a loss can be a great decision. I'm all about taking small losses so I can find another trade and let my winners run. Otherwise you might be stuck holding the bag for weeks, months, years. And the biggest problem with bagholding is the emotional toll. A lot of people wait and wait and end up selling near the bottom when they can't take it anymore psychologically.
