The session shadow: the two ends of a fortnight a session cannot see

A client’s fortnight is organised by the date of the next session, not by the plan made at the last one. Both ends of that gap sit outside the coach’s view: the far end because nothing is due yet, the near end because it happens in the hours before you meet. Call the stretch the date governs the session shadow.

One r/ADHD commenter does not pay the electricity bill until 8:58, two minutes before shutoff.

What is the session shadow?

It reaches both ends of the fortnight, for opposite reasons.

The far end is the scramble, which coaches already know about. An r/ADHD post titled “My only productivity comes from panic” drew 1,146 points and 183 comments from people describing work that only starts once failure is close enough to see.

The near end is the one nobody in a session can see, because it happens in the hours before the session starts. A second r/ADHD thread, about one afternoon appointment swallowing a whole day, drew 239 points, and the top reply at 77 points gives the community’s own term for it: “Ah, ‘waiting mode.’” Another poster there gets nothing done in the hour before they have to be anywhere.

So the coach meets the client inside the waiting-mode hours, which is a poor moment to ask what a fortnight was like. That is a sampling problem more than a coaching failure, and the session will not show it to you.

Does a shorter gap fix it?

It moves the date, which is the only part of an interval a coach controls. Nobody has run a trial on session spacing in adult coaching, so read that as a mechanism and not as proof.

The nearest evidence is next door and it is about students. García’s 2025 study of mentoring frequency reports four or more mentoring sessions reducing dropout and improving academic performance, while three or fewer did not. Mentoring undergraduates is not coaching adults, so take that as a direction rather than a dose.

Search “between coaching sessions” and nearly all of the page is about the session: what to expect in one, how to structure one, how to stop one running overtime. One result is a Reddit thread whose author hired two coaches and got almost no engagement between sessions from either of them.

What should you ask instead of “how did the two weeks go”?

Ask for a date. Which day did the plan stop fitting, and what else was going on that day?

I gave that question a piece of its own in the decay date. A date can be checked against a calendar, while an account of two weeks gets assembled at the table.

Then put a second date inside the gap, on about day three, while the plan still looks workable to the person who made it. Five minutes of writing due on a named day beats a list due sometime before the next call. The fade that comes after has its own shape, which I wrote about in the novelty subsidy.

You cannot supervise the gap. Put a second date in it, and let the date do the work it was always going to do anyway.

Questions people ask next?

How often should coaching sessions be?

No trial answers that for adult coaching. The nearest evidence is García’s 2025 study of mentoring frequency, where four or more sessions reduced dropout and improved academic performance and three or fewer did not. Those were students being mentored, not adults being coached.

What should a client actually do between coaching sessions?

Something with a date attached to it. The r/ADHD accounts of panic productivity and waiting mode both describe effort arriving on deadlines instead of on intentions. One task with its own day travels further than a list meant to cover two weeks.

Why do clients arrive with nothing done?

Often because nothing was due. One commenter in a related r/ADHD deadline thread dropped four classes on learning that assignments were only due by the last class. A semester of work would then land on one day.
