Writing a memoir can be very challenging. Besides all that goes with the writing process of getting your story down on paper, there are also challenges such as where to start your story, how to tell your story in an engaging way, and which writing techniques to use so you can express yourself effectively.
One of the hardest parts of the writing process is getting honest feedback. Close friends and family think nothing of lying in order to spare your feelings about as little as a poem. So they'll sooner tell you that your baby is ugly than that they didn't like the manuscript you've agonized over for two years.
