20150603 Long time no see.

For last 2 weeks, I have suffered by pain. I got surgery and be hospitalized.
By this experience I realize that if body is weaker, mental is gettig weaker too. I have studied English and programming for a while regularly before, but when I was in pain, my will was falling down, and my plan to study was messed up.

So, now what?
Health is the most important thing than ever.
