If you see it as an opportunity, that's almost a couple dozen pages--including a cover page, appendix, and index, of course--to reflect on yourself for free.

No reason it could not be expanded later to motivate other projects.

Literally people are asking to read something you wrote, as a captive audience. Already made the sale (at least the first few pages).

I would have had the same knee-jerk reaction a decade ago, when words were cheap and life long. Now there is less time for everything.
