It’s a year from now and my plan failed. What went wrong?

I’ve decided to . Here’s how I intend to do it: . Imagine it’s a year from now and this has clearly failed. Write the most believable account of what happened, as a short timeline looking back: the first thing that slipped, what I told myself at the time, the last point where it could still have been saved, and how it ended. Base it on how plans like this usually fail, not on freak events. Then give me the earliest warning sign to watch for and one change to make now. Don’t reassure me. Finish with the second most likely failure in one line, and what you’d need to know about me to tell which is more likely. Be direct. No padding and no reassurance I did not ask for.
