I'm addressing this one by
trading via a demo account. I took my time and played with it until I was comfortable with the interface, and now I am trading several thousands of dollars (in play money) per week without
fear. When I am properly trained, I will begin trading with real investment capital.
We fear the unknown. We fear failure. If we fear trading it is only because we know that our lack of experience (what we don't know) will almost surely lead to our failure in the short term. Robert Kiyosaki, in his book "Rich Dad, Poor Dad", says that he doesn't know of any rich people who have never lost money. Think about it.
Rich people lose money. Yet they still succeed in making it. They challenge failure and, though they lose money sometimes, they succeed at what they do.
Except, of course, for the losers who break a gazillion federal laws in the process and get sent to prison for two hundred years!
The
fear of trading can be addressed by learning how to trade, and how to manage our risks while doing so. With a demo account, the only thing I'm risking is my time. And the only way I'm losing that time is if I don't learn from my mistakes.
