Have you ever thought about writing the story of your life?

Why not!

Well , no but partily the writer always put some of his life in what he/she writes 

Many times over, actually. But writing one's own story is writing a diary....and both are very toughy jobs requiring soul searching, pursuit of truth and understanding of one's audiences.

Not yet.  I mean, I still have a lot of topics to write about to turn my attention on myself.
