For the first time I am writing a biography, and began reading about the best biographies. I found two points to keep in mind, which are immensely useful.
Firstly, every detail of the person’s life does not need to be included.
Secondly, write after identifying with the person, try to see life and the world through his/her eyes. This second point definitely gave me a different perspective, instead of looking at the person through the accounts and views of others. It gave me a much better understanding of the person about whom I am writing.
