Make a map of your failings. Broad rough estimations. Fine details. Multiple dimensions. Multiple definitions of failings. Timelines and categories.
How are they related or not? What are the patterns? Is there a build up? A wear down? Spurts and droughts?
How bad were they, really? How many lead to something new? How many lead to something interesting? How many just washed away with the creek? How many are still haunting you?
Can you not fail? Is it ok?
Who is speaking when you draw all this out?
