I looked at the date of BehStrLearning1.doc file which is the first document file of my current paper and it dates back to 7th of September 2004! It means that I am working on this paper for about 4 months! Wow! I wouldn’t believe it if I were told that a paper writing might take this much long time. Hopefully, it is in its last parts and I wish(!) it will finish and be submitted very soon.
