You need to be a bit more clear about what exactly you are trying to say because from just that line alone I could write 15 hubs on it alone. Try and be more specific on the question, in that way we other hubbers can narrow it down to exactly what kind of answer you are looking for.
With that said let me take a long shot on what I think you are asking.
If you are referring to how to rewrite an article but with a similer message you just have to look at the context of the article, most of the time you can substitute one word for another of in some cases one phrase for another but yet it could still hold the same meaning. for example is the following.
1) Photography is a very fulfilling job that anyone can have.
2) One of the most fulfilling jobs to have is photography.
Hope this helped you out if not just a little bit.
If your just looking to make your hubs longer then well look at the example I just did answering your question 8o).
just started with a few lines and as I was writing it other things just kept popping up in my head that I thought was relevant.
May god bless all who blesses Hub Pages with their writings.
