In the process of searching for a new focus [for your life], it is almost inevitable that the "big" questions will creep in. There is pressure from pseudophilosophers everywhere to cast aside the impertinent and answer the eternal. Two popular examples are "What is the meaning of life?" and "What is the point of it all?" There are many more, ranging from the introspective to the ontological, but I have one answer for almost all of them--I don't answer them at all. I'm no nihilist. In fact, I've spent more than a decade investigating the mind and concept of meaning, a quest that has taken me from the neuroscience laboratories of top universities to the halls of religious institutions worldwide. The conclusion after it all is surprising. I am 100% convinced that most big questions we feel compelled to face--handed down through centuries of overthinking and mistranslation--use terms so undefined as to make attempting to answer them a complete waste of time. This isn't depressing. It's liberating. Consider the question of questions: What is the meaning of life? If pressed, I have but one response: It is the characteristic state or condition of a living organism. "But that's just a definition," the questioner will retort, "that's not what I mean at all." What do you mean, then? Until the question is clear--each term in it defined--there is no point in answering it. The "meaning" of "life" question is unanswerable without further elaboration.

I think Ferriss has a good point, but I also think he's kind of dodging the question by not taking the further step of explaining to the questioner exactly what the questioner is curious about and what can be known about that curiosity.
