Homesickness?

Can one tell by the amount of homesickness that you feel, how good/bad your stay abroad is? Does homesickness mean that your stay away from home is bad?
Having been on an exciting travel for 2 weeks now I still miss my friends and family at home from time to time. But I still want to be here. Every day is different and every day I learn new things about Japanese life and language, new people. Although Japan is not the ultimate thrilling experience as I expected before (I probably listened to too many people praising Japan - in restrospect everything seems even more exciting) we start to have a lot of fun here.
For me homesickness means that I stay realistic, have not lost my connection to home and not get my head into the clouds. Don't know how to say it, but I experienced it before when I was in the US, Vietnam and France. Having a temporary new life should not make you forget your "constant" life for too long. I guess missing the people at home is a good sign, because it means that you know you have something precious.
When I was in the US I was 16, in Vietnam I was 19, and when I went to France I was 21. Back then (Oh God I sound so old) my travelling was like an overwhelming odysseey, changing me alot, making my life a rollercoaster for some time. And then I had much trouble finding myself and my place when I came back. I feel much more calm on this stay abroad. This time, in Japan, I feel that I have found a constant string in my life. This travel for me is "just" a little adventure I take from my life that I can slowly start to make out for the future.


My friends are starting to make fun of me and my blog! But that's a good sign, right? ^_^ I miss you guys!
