In general, i liked this book. depending on the current life situation, the parts are differently appropriate and helpful. I once again felt the need to mark certain sentences while reading in order to find them again later.
Basically, the book is very positive and well-worded. I think most people can take something away with them, even if not all the tips are completely new.
There are also many exercises included. not all of them appealed to me right away, but again, i think it depends on the current life situation.
I found the writing style very fluid, pleasant and easy to understand.
