Noticing Newbies

I would like to learn to write in a style that would allow me to express ideas such as
https://www.writing.com/main/view_item/item_id/2244186-if-only-oxygen-would-stic...
in a clear and concise manner.
instead, I make stupid mistakes. it should read technical and non-fiction writings.
my purpose here is to improve my language/presentation skills. in that way when I post the ideas on an ideas forum such as the half bakery, they will not be pulled apart over some language error.
