Writing is a struggle about finding the right word. Or string of words. You need to be able to convey, to describe, to paint, and do it all in as few unnecessary words as possible. Which is a whole lot easier than it sounds, believe me. So I’ve used these two, on occasion – and they do help:

Hope those help!
