English or no Englsih

I may never become a writer. When I saw how my little email was edited in all sorts of unexpected way, I think I will never become a writer, in English and Chinese too.How am I supposed to know the difference between "Thanks for your interest in our exhibtion" and "Thank you for your interest in our exhibition"? A very hot day today, which makes me feel my laziness at work are all justifiable. If I can not become a writer, what can I become? If it has so many difficulties at the moment, will try harder helps me eventually fulfill my dream? Will try harder can make anything happen? What if it never comes, or comes too late that I lose my interest?I don't know.All I know is that I will still be writing lots of English letters with lots of mistakes in it.
