Fear is natural, even healthy. It makes you cautious when you otherwise might be too careless with your money.
But trading forex - like anything and everything else - isn't about "not being afraid." It's about controlling your fear, and using it to your advantage. It means being a smarter trader, and knowing when your fear is telling to to take a step back and analyze what you're doing before you do it.
Not being afraid at all is, IMHO, reckless. Just don't let your fear paralyze you into doing nothing.
I think the only individuals who trade without any anxiety are the total newbies who don't yet know enough to have anxiety. That was the case with me when I first started.
