taking old stories from a close writing sites and reposting them here in a new style

With my stories from my kites that I am now putting on LB since I need 300 word for the stories . The stories are kind of now new stories since I am adding to the story that I wrote before . The hard part when adding the 300 words rembering what the story is about I read one of my last post and some how the story when some were else I rally do not know how I do this ? Or maybe I get carry a way. Has any one else taken there story or post from a site that is now close down and had to ad words or characters to the story so you have the right numbers. This take times for me some time it relaxing since I enjoy writing stories and some times it hurt my brain. Why does it hurt my brain because I have to use it. I know my brain need to be use . Because my normal job I rally do not needed for the job I do and it make me get bored . I hate being bored what about you ? would you rather use your brain for work or not use it ? Yes I know this sound like a joke but it is not. I am now checking the post that I did save from mykites to see what I want to post and how to ad to the story post that I am doing. I enjoy doing short stories I think my stories will be good for kids young ones. But I know some adult will and will not like my strange let say young kids stories. other part of me would like to write children books to make money .I know the children book market is hard to get in. As you see I am now some were else when I was talking about taking my kites stories that I posted and adding word to them to post them here on LB. OK that it for this one have a good day.
