As quoted luck plays an big role in profiting, though the person doesn't have much skills. At the same luck won't give a constant earning, because every time luck won't stay with certain persons. Skill is not like that, we can make strategies and move on to get a constant earning. I believe that the person with skills is always lucky.
Yes indeed, luck is the basis for profit. Even so skills are also indispensable in trade. Because if we use trade only rely on luck it will not be profitable, so it is very necessary skills. With the skill we can increase the chances of luck.
