It is important to remember the distinction between the way we write and the way we talk. I'm not saying this so you are afraid to write out your ideas like you were talking to someone. Instead, you should get your ideas down first, then go back and see how you might word the ideas better. When we are talking to someone else we always have the ability to further explain ourselves if that person does not understand us; however when we write, we put our ideas into words. When someone reads our words and ideas, the words cannot tell if someone understands, nor can they explain what it is you are trying to say.
