How many times have you found a stock you like, did your research on it, and were ready to pull the trigger, only to talk yourself out of it at the last minute? And then days or weeks later, you come to find that stock has shot up, and you're now kicking yourself for not being in it. After having that happen to you one too many times, you vow to not let that happen again on your next stock. You still have the same unease as before, but you decide to get in anyway. Only this time, the stock immediately starts going down, and you instantly regret your decision. Of course, with that recent loss fresh in your mind, you decide to be more diligent. But you wind up talking yourself out of your next trade, only to find that stock has gone up just as you had expected, and you're once again, not in it. This cycle can repeat itself far too often, creating scores of missed opportunities, making people hate the market.
