I am trying to write the first paragraph of a story, but I keep on backspacing every time I get to the second clause of the first sentence. I want it to sound right, but it doesn't. Should I just write the paragraph without focusing on whether its sounds right, and even whether it makes sense, and then revise it afterwards? That's one thing that is difficult for me. Writing without paying attention to sound and structure? Do people often write without structure, and shape their writing later?
