When they have to write a text, writers have generally to think, to anticipate, to foresee what they will write. This anticipation can involve the content (what has to be told) as well as the linguistic form (how to tell it) of the text. It is besides common to think that the longer and/or more intensive this reflection activity will be, the easier to write and the higher the quality of the text will be. Consequently, this text will not need any important modifications or corrections afterwards.
