Why does nobody talk about the glue wait in handmade books?

I bound a sketchbook for the first time last week. The glue between the cover and pages needs a full day to set right. I rushed it once and the spine came loose. Now I set it under heavy books for 24 hours exactly. This wait feels endless but it's key for a strong build. I listen to old radio shows while it cures. That way, the time passes with some fun. The result is a book that lasts, with no screens in sight.
