Being an "M" (instead of a "T")

This summer I've been introduced to the notion of becoming a "T" person. The shape of the letter is analogous to one's areas of competence. For example, a "T" person has depth in one area (the vertical bar of the letter) and a wide area of superficial knowledge (the horizontal bar of the letter).

During a conversation, I realized that I'm a "M" person. I start with two pillars of competency (the outside bars of the letter), and then I return to the superficial level of each bar and drive toward a center (of lesser, but still significant depth) in between the two pillars.

The fun part is that I know one pillar is music, and the other is science (probably computer science/math as I delve deeper), but it's still a process of discovery!! Or maybe I'm totally wrong and the pillars will turn out to be something else! Well I know that one will be music anyway... :)
