I seem to have wanted a field of technology as my occupation. But why has it been so? I ask myself and I find that probably it is because I feel I could find some sense of something futuristic in technology.

But what is it that I refer to by the word of "futuristic"? It must be some academic depth and arcane complexity or something. And the sense of something cutting-edge. Why those things? Probably because I feel some sense of life in them, something lively, something creative.

But if so, what I could find such may not necessarily be in the field of technology. And I think I must think what I can do in my life is quantitatively limited. It might be that I should do what I find myself happy doing, so that I not regret later my not doing what I really wanted to do.

So it might be this: not that I choose my occupation, but my nature somehow leads me to it.

In this sense, you can think that one's vocation is not what you choose but what you are given. Vanity may hinder you from doing what you are really fit for.

Cost-effectiveness, synergy, opportunity cost, and comparative advantage ... those things can make me think which field of job I should go to.

In the field of technology, I have to keep on studying, of course. And if I go to another field I may otherwise go to, it does not change. Then I can ask myself: which is it that you can do more readily? In this regard, it seems to me that it became quite clear.

The competition of job must be severe in both fields. And efforts are needed no matter which field of the two I go to. And both require much time to acquire decent skills to perform the job.
