how do i start to write a onepage reflection on this quote'' making the decision to have a child is momentous. it is to decide forever to have your heart go walking around outside your body - elzabeth stone
Don't worry about starting the paper until you've finished writing the rest of it.
Make a list of things you want to include in your reflection. Then write them up. By the time you finish, I'm sure you'll have thought about a good introductory sentence.
