After choosing this one incident, you will write an essay which will carefully balance a narrative description of the writing event, itself, and an analysis of why this event has affected your current view of writing so significantly. You may find it easier to write the event in a sequential fashion first (making sure to pay attention to all important details); then, write an analysis of the event (i.e. how/why it affected your view of writing); and finally to combine both narrative and analysis into your final essay.
