Mission completed again

Hi All,
I sit here in Fukuoka in my hotel room, after having finished a long course, a PANS-OPS basic. You know, they are 2 times 3 weeks with a break in between. This time the break was planned around an OCP meeting in Singapore, so all in all I have been on the road in Asia for two months now. It is always the same after a long course/trip like that: a weird mix of feelings. On one side I am happy the course is done and I could help a big class to achieve their training objectives. I am also glad to see my people at home again after a while, I look forward to sleeping in my own bed and I look very much forward to the Christmas holiday, as it has been a very good, but very busy year and I need a break.
On the other hand I also feel sad to leave what has become a part of my life during the last two months: my hottel room, the students, the supermaket next door, the old train that takes us into Fukuoka City, the female voice that announces the stations (about 20 seconds in Japanese, 3 seconds in English... anybody seen "Lost in translation?").
So it's always a farewell to something that became part of the life for a while. Ok, you could say I am used to it, as I constantly do this. I am used to it and I know what's gonna happen at the end of such a course. Nevertheless, the feeling comes and is quite strange. I think it makes me realize everytime that life means motion, moving on, and that we cannot hold on to the past.
