The loaf cut too early gives away something patience would have kept inside.

Impatience has a physical cost here. Cut while the inside is still setting and the steam escapes, the crumb collapses slightly, the texture never recovers, and what you lose was already made and simply not yet finished. The bread was fine. The timing removed part of it.

When you are close to the end of something and want to see the result, put a small delay in the way rather than relying on willpower. Set the loaf somewhere you are not standing. The same applies to sending things: the version you look at tomorrow is usually better than the one you could not wait to release.
