No gambler can beat his or her chest today to say that they have been able to completely eliminate the fear of making the wrong decision when gambling. I have a philosophy that says that being over confidence about things that are naturally uncertain can end up leading to more mistakes. The ability to be afraid is sometimes all you need to make the right moves, but everything has to be properly moderated by you as an individual.
Gambling is ordinarily an unpredictable matter, the only reason why we are able to make accurate predictions about certain gambling games is simply tied to our level of experience playing those games or watching them. The more experienced you are the better you may become placing gambles. As a result, it is good to always work hard towards gaining knowledge but more importantly, experience in gambling.
