Why should writers avoid personal pronouns?
Several reasons. First, it gives your writing less authority by making the reader conceptualize your arguments as statements of opinion rather than statements of fact. Second, everyone knows that writing is the author’s opinion. There is no need to remind the reader of something they already know. Third, personal pronouns are completely useless, and add unnecessary bulk to your writing. The majority of personal pronouns can be removed making the writing stronger overall. If you are having trouble with this, the best way is to write everything out, then come back and edit what you’ve done. Writing is much easier to work with after its on the paper (or the screen).
