The following quote is attributed to American poet Ezra Pound (October 30, 1885 – November 1, 1972):
What matters is not the idea a man holds, but the depth at which he holds it.
In other words, a person may have an infinite number of activities, or may be preoccupied by an infinite number of details for a single project. The number, however, will only have proper meaning if the person pursues said project with a definite purpose.
Thus, the what of any human activity (What am I doing / going to do?) does not have as much bearing as its how (How shall I go about doing what I intend to do?). Then even the how is trivial compared to the why (Why am I doing this?).
