This is an interesting question to discuss. Working smart is at least more pleasant than working hard and I believe that it is also generally more profitable. However, I don't think that relying on luck is smart. It is truly risky. I think that smart work is rather about thorough development of the ideas, high level of rational success predictability, not luck attraction.
I see your point and I don't particularly disagree with it. But I didn't mean you should rely on or hope for luck alone. You can continue to work hard for your boss as always and still be looking for an opportunity or chance to change your life dramatically to the better. Let's loosely call that working wise. Basically, all I wanted to say was to emphasize that you shouldn't discard or write off the importance of luck completely. Ignoring a stroke of luck when it happens all of a sudden against all odds would be the most foolish idea that you will likely regret for the rest of your life. In this manner, it makes sense to work toward increasing your chances of meeting Lady Fortune one day. For example, if you want to be romantically involved with someone, it means visiting places where your chances of starting a romantic acquaintance are the highest.
