How much I am inspired after reading.
By reading it.
Interesting question. I guess: by how much I enjoyed it; what I learned from it; what it made me think about; how well written it was; how it made me laugh.
Unable to put it down once I start reading it...currently reading one that I have in one hand while the other hand is on my keyboard, because I am now one with the book
until I finish it.
With a ruler.
Looking at the price tag?
first i read it, then i decide what it is worth to me..
