perspective
Since then, I've been working as a full-time programmer (for my open source projects, waon and ryuon) and one whole week had passed. This is one of the things which I wanted to do for a long time. During these days I have nothing preventing, no complaint for lack of time, no pressure from others (but only myself). Now I can feel something about what (and how much) I can do in a long run, in other words, my ability.
As a second step, for time being (not so long, unfortunately), I would explore other sides further in one hand, and figure out some more real and concrete things in the other.
