T asked me to write a time line of my life.
started with large milestones (moon walk, graduation dates, stuff like that) and thought about where we lived
then I filled in the years we lived here & there
and birth /death dates in the family
it came together after a while
then I put in my own events - marks up for good things, marks down for bad things.
It was hugely illuminating.

Best of luck to you... you didn't ask for opinions but looking for yr biggest boogeyman first sounds very scary to me. personally I would have to start at the other end. take care
