Thread: Check my pronunciation, please

This is my 3rd try of the book fragment narrating. Check it, please.
<<<Video deleted>>>

General questions:
Which words sound good (maybe excellent?)
Which words sound acceptable
Which words sound bad (which sound)

I tried to improve my intonation a bit (thanks Rokzmom), but I don't consider it that important at this my stage of learning only sounds themselves.
I'd be very glad if some of you could post it like:

During the first thirty-five years of the twentieth century, the
publishing houses of America printed more than a fifth of a million
different books. Most of them were deadly dull, and many were
financial failures. "Many," did I say? The president of one of the
largest publishing houses in the world confessed to me that his
company, after seventy-five years of publishing experience, still lost
money on seven out of every eight books it published.
Why, then, did I have the temerity to write another book? And, after
I had written it, why should you bother to read it?
Fair questions, both; and I'll try to answer them.

Red - fail
Yellow - not bad
Green - good

Just comment as many words as you can. Or maybe just some overall notices about what to correct, except intonation?
Any help will be great for me.
Thanks in advance.
