In most other professions, activity and returns (or success) may have some co relation. At least hopefully they are not inversely related. So all our parents tell us to put in hard work. In trading too work is required, real hard work is required to understand what the hell you are trying to do. But then the comparison strays away. The more activity one does is trading lesser could be the returns. In fact most successes happen by patiently waiting and not acting. Thus one important trait for successful trading could be laziness.
It is not easy to wait till time stops for the right framework or setup to appear and present itself for the killing. Most losses happen when one can not wait for that opportunity.
