"Life is a risk" is one thing to tell you that whatever you do or engage yourself into, there must be a double side to it. That is, negative or positive. But they say the worst risk is not to take risk, and so as a human being you must take a risk to survive.

Yes some people criticize trading because they see it as risky and that it is illusive as you don't know who you are dealing with but that risk they criticize is what they face dealing in their physical dealing which they either lose from or they profit just like an online traders would too. There is no aspect of life that is not full of risk but what is important is to ameliorate the risk. As a trader, you don't need emotion or sentiment. What you need is use proper risk management strategy.
