I'm sorry for that! All other sections were written nicely or OK, and I appreciate for what I picked up from the book. I just wanted to point out some places needed to be reworked in case you continue.
Myself being in industry, I know how hard, near to impossible it is to find time for anything extra than work and family. And a decent book requires approximately the same amount of effort as finishing PhD. Perhaps that was my frustration coming out of the projects I had to abandon. :(

I have to say comments like yours are not really encouraging to continue writing ;).
