My advice would be to read a couple of critically acclaimed autobiographies to get a feeling for how you can avoid making your story an endless, boring recitation of facts, dates and names.
I suggest The Autobiography of Alice B. Toklas, David Niven, and Testament Of Youth (Vera Brittain) but there are lots of good ones.
Most that I’ve read begin with an explanation about why I would even care that the author lived and/or is sharing intimate details. (Say, for instance, you went abroad to work with the Peace Corps and ended in brutal prison in a foreign country...what about your early life prompted you to do such a daring thing, what were you like before, during and after?)
A strong suggestion directly from me. Few things annoy me more than an autobiographer hints throughout the book that there is one or more things he/she did or someone else did to him/her that would positively knock my socks off ... and then I’ve gotten to the end and the BIG THING was never discussed. If you’re going to withhold things, don’t mention or even imply things.
