Certainly.
I believe regular practice is what will help you to overcome your fears, experience teaches a lot so yes the more your practice, the more fearless one becomes with time. Isn't it?
A trader has to be very alert in understanding the market moves. For that he needs to have a strategy well in place and sometimes there are even times that circumstances lead you to change your strategy for favorable results. So uncertainty is very common, we need to know how to deal with it.
