I think the very first thing you can do to overcome your fear is that start small and see how it goes for you. At least in my case, I started around $200-$500 and try to get the feel of the system. And somewhere along the way, I lost but it gives me a valuable lessons that I wanted to come back and not to make the same mistakes again. And so as I go along my trading or investing journey, I gain confidence, learn some trips and trade and now I totally overcome my fear. Of course there's no perfect investment, you lose some, you win some at least you made that very first step and who knows, you might find it very attractive and challenging at the same time. Goodluck.
