You may hear your friend say, "I have a great plan for making a huge profit … bla bla bla…". Stick on your own risk profile and then stick to it as an investment strategy. Invest to the extent that you do not exceed your risk profile. Your friends might give suggestion on how to make good profits, but they not have the same your risk desire. People have different risk profiles. When they make a loss, they almost not tell you failure.
