That true mate I agree with you that Trading is not easy. In trading you will be need a lot of effort. Thus, you also need to be aware himself form all the knowledge that is required for trading. Apart from this, the most important thing is experience, which is a very important thing for every trader. Trading without experience + knowledge is like gambling. That means to become a good trader, you have to learn all these topics which are not within the reach of an ordinary person. In which one has to learn things like knowledge + experience, technical analysis, fundamental analysis, market sentiment, dynamics, etc., which is a very difficult task. And above all, it is not to be learned but to be monitored and applied as soon as there is a suitable opportunity. 
 
So you are right that Trading is a very effortable job.
