Writing is hard when you really try to make it right.....

I thought i had writing down to earth,but guess what i didn't.I see that i write like i think and thats simple without any expression.I want to make my writing more creative,but really don't know how.I wonder why is it that we sometime can talk professional,but not write it.I need the help so to my classmates thats good with opinion i am open and willing to take what ever you throw at me cause i want my writing to improve as much as possible.
