PLACEHOLDER POST – replace before launch.
Preparing has a stopping point. Overthinking does not. Both feel productive in the moment, which is what makes them so hard to tell apart while you are in the middle of one.
One useful test
Ask what new information the next hour will produce. If the honest answer is none, you have moved from preparing into rehearsing a fear.
What helps
Decide in advance what finished looks like. Written down, before you start, where the tired version of you can still read it.
