i try to learn from my mistakes, but what I like more is learn from other people mistakes.
I analyze their experience and try to avoid same actions if they cause to loss or time wasting.
That is a great way to learn, there is no point in making mistakes when you can learn from the mistakes of others, this is why the forum is a great source of information because not only you get to see the successful strategies that people use to get money in this market, but you also get to see the strategies that they use when they lose money and that kind of information is worth a lot.
