The Mom Test, the entire book, is a couple hour read... honestly if you have any interest at all in selling or building (or simply work at a startup) it's worth reading the whole thing, and not a summarized recap... the book itself is summarized.
You're completely right thats what I say as well.
If you're interested in this topic, read it it is barely 140 pages long.
But I think a summary can be a good intro and a good learning for me as well :-)
