I just pre-ordered this book and think it's definitely worth it.

Full disclosure: I have no affiliation with the author, but I'm sharing because I genuinely believe in the work.

Why do you say it's worth it before you've even read it, let alone seen it?

It’s worth (for me paying that amount of money for) it.

We all do this kind of value judgement before paying for a product we haven’t yet evaluated.
