First, go back to basics. The whole idea of article writing is to communicate. You have found good information, news, drama, or opinion on a timely subject and feel you have something to say about it. Perhaps you have no more to say about it than any one else but your way of elucidation may help people to see something a little better or something they may have missed. This is good stuff but then comes the business of writing it.
I have found myself getting too long winded in some of my articles. When I found out that the best article length in general is between 450 to 650 words I started to modify my writing to fit that criteria. I still get cramped up sometimes wanting to write more but knowing Ive said enough. In time I found a way to keep things both simple and readable without sparing important content.
It is so simple I am almost embarrassed to say it. But if a thing works it should be made known. If you were to pick up a pen and write a letter to a friend what form would it take?
Would it have a summary, seven points and a huge wrap up? No it wouldnt. What it would have is three major divisions, an introduction, two or three points and a conclusion....
