Contrast that individual with someone who sporadically follows up on the priorities and commitments he's set for himself and learns based on his whim or mood. While this second person is involved with the goodness, Torah, and spirituality to some degree as well, he is involved with it in a non-spiritual manner. This second person's learning is going to be dependent on a whole slew of physical, natural, and inclination-oriented factors (i.e., what his day brings his way, his mood, etc.).
Clearly, designating a time and/or place for Torah study and all that truly matters is the most appropriate and effective way by which we can learn Torah and grow personally. After all, it parallels what Torah itself is all about; just as Torah lays out the deliberate and orderly manner in which one is to direct and apply his will over the randomness and chaotic nature of his thoughts, emotions, and desires for the purpose of bringing out his soul-side and manifesting God in the world, so too, the learning of Torah in a deliberate and orderly manner—as opposed to an arbitrary or wishy-washy manner—is most appropriate and advantageous to the Torah learning itself.
