Then one day it was like she crossed the line. She became like a newscaster, she never turned off, was always in this weird fake space.

I have no doubt that it has practical applications in the business world, but on a personal level she lost her sense of self and became like a weird robot version of the girl I knew. It might be due to the age at which she read it, maybe she was too impressionable and took the philosphies and practices too much to heart, but IMO she lost probably about as much as she gained from it.
