Trading is hard work at the start, but it should be effortless during the trading process. Good or professional traders know this. In fact, trading should be boring to some degree when you have your system and methodology down. The reason for this is you know when to pull the triggers and when. If something happens, you know what to do. You know how to react when the time is right. However, it requires hard work to get to this level. It's all about discipline.
When you get ready for anything, a marathon, football game, tennis match, etc - typically the preparation of that is much harder than the actual match or game itself. Take David Blaine, the man who held his breath for 15 minutes under water. When he discussed how he did it, he mentioned he trained for months. He lived in oxygen deprivation environments for an extended period of time and it required a lot of training. When it came time to actually hold his breath, the event only lasted a merely 15 minutes. However the training took several months and a great deal of pain to get there.
Think of trading in the same way. The action of actually executing the trades is easy. It will be easy for you to hit the buy and sell triggers - whether you are successful or a failure that will depend on the training and the hard work you put in before you execute your trades. If you work hard, study, and put time into it there is no reason why you can not be successful. However if you follow everyone else, do not put in your own time, or don't do your own homework - you are just in for a crap shoot.
