linguistic analysis : help needed

Hi guys,

I have a big problem dividing this little text into clauses using this conventional signs:

||...|| = clause
| ... | = functional components/ groups
[...] = embedded Prepositional phrase
= embedded (downranked) clause

Dear Reader:

On a beautiful late spring afternoon, twenty-five years ago, two young men graduated from the same college. They were very much alike, these two young men. Both had been better than average students, both were personable and both—as young college graduates are—were filled with ambitious dreams for the future. Recently, these men returned to their college for their 25th reunion. They were still very much alike. Both were happily married. Both had three children. And both, it turned out, had gone to work for the same Midwestern manufacturing company after graduation, and were still there. But there was a difference. One of the men was manager of a small department of that company. The other was its president.

What Made The Difference

It isn't that one person wants success and the other doesn't. The difference lies in what each person knows and how he or she makes use of that knowledge. And that is why I am writing to you and to people like you about The Wall Street Journal.

Does anyone know how to do it? I've never seen this kind of exercize
