Today my feelings are quite complex because my friend of many years will leave the same company very soon, next Friday.  We have been very close.   We talk about almost everything, studies, publications, work, life philosophy and even sex all the time.  Some thing like one should work to live or live to work.  We both think that we should live to work.  But the majority of people will try to work to live.  On the other hand, I am very happy for him because we talked about going back to China to serve the country a lot.  But this time he put this discussion into reality. He is leaving for China for good this time. Of course he will be back for conferences and scientific meetings.  But his life will be mainly in China. He will serve the country with his knowledge, his training experiences and his loyalty.  It has been a life time learning experiences for both of us.  He will have the new beginning of his life. March 28^th will be the day of his new beginning. It is not an easy decision.  In China the income is not as high as in this country.  But in China if one has a good position, one should have much decent life there.  I have a lot of thinking today, thinking of my friend, thinking of my self and my own future.  What am I going to do?  I am in the very critical time as well.  If I can catch the moment, I still have a chance to do well in the rest of my life.
