My take on the text is that activity and success are not synonymous. Clearly, the article has a commercial bias. However, “industry” in the original sense of the word does not necessarily mean the accrual of money. Many modern time management books, articles, blogs, and magazines reiterate the same need for discipline and concentration of limited resources (particularly your time) on the most profitable (meaning best outcome) tasks at hand. See for instance, “Eat that Frog!” by B. Tracy, and others. If your objective is to enjoy your life as you wish, then set your sights appropriately and work toward this goal not with fruitless activities but rather those activities which are most likely to advance your goal the most.

I have recently been considering this idea of activity vs. energy. I often feel that I do much, but do not get much done. I will be experimenting with minimalism soon, and one of the areas that I plan to focus on is where I spend my energy/time. I want to choose some select goals and focus on them. I can’t wait to see how much progress I make with this conscious focusing!
(and no, my goals aren’t all winning and money)
