I realized this weekend that my areas of generalization are starting to contract a bit.
Part of it is really just simply the factors of time and money. I find that my time, although differently distributed since I changed jobs, has not experienced a net increase in terms of availability. As a result, when to do certain activities has become a bit circumscribed (after all, throwing heavy things above your head after dark is not a recommended activity).
Money. Suffice it to say with the continued increase in taxes and upcoming college phase (we could have college expenses for the next 10+ years), budgeting matters more than ever. And thus, the likelihood that a new activity will be "invested in" at some level based on a passing interest becomes less and less.
But there is another factor that I am coming to appreciate: the power of expertise and specialization.
Being a beginner at everything gets to be discouraging at some point. One begins to desire some level of expertise at a thing, from the practical sense of accomplishing something and the emotional sense of being able to accomplish it. This requires a level of focus on a particular set of activities - and thus by default, a degree of specialization in them.
I have been considering this over the past weekend as I was about my business, taking stock of what is going on in my life. Simply put, I could just work on the interests I have going on currently in my life for the rest of my life and not reach the outer limits of any of them. I could probably also scale back my energy and time on some and still have enough to keep me interested and engaged.
Do not get me wrong: I will probably always be a generalist at some level, if for no other reason than being able to do a great many things turns out to useful. But I also need to make peace with the fact that in order to advance meaningfully in some things, there must be focus and specialization - and a corresponding change in focus and energy.
