If people want to avoid more bigger problems then maybe they should start eliminate the fear in them and go to the right person that can teach them on how they can possibly teach to became a pro. Traders should not go beyond on their capacity like they only trade what they can afford to lose at that time, since for sure their experience towards trading is satisfying especially if they develop some useful attitude that can help them to do good trades..
finding someone who can teach them to trade is a good move. it would even be better to do so before they start or try trading on their own. We know that sometimes there are people who try first because they are curious. but after they fail they look for someone to teach them better. Experience always provides valuable lessons. but it depends on the trader himself, whether he succeeds in taking lessons or not. If it doesn't work, maybe what happens is that you fall into the same hole several times.
