Incredible waste of time.
Do two things:
One. Put in title a very clear indication that the book is for humanists, beginners, people who never did mental math, and that it gives you very basics. Make sure if an engineering grad reads the title he would skip over it and not even think of buying it.
Two. Remove all the 'inspirational speech' bullshit, stupid real world analogies, and stop repeating yourself multiple times, like you're practicing hypnosis. This is practical tech. stuff, it's not religion, nor philosophy, nor a hypnotherapy session.
I've listened to 35 mins of the book, that's 64% (couldn't handle more), it were probably the most unproductive 35 mins I had in years. Supersimple stuff delivered super slowly. I had answers a second or two after the author was finishing reading his example.
Two stars instead of one, because I think the book may be still (marginally) useful for people with non-technical degrees, or for children. Although it still has good deal of dangerous 'inspirational speech' type of brainwashing.
