Change is the only constant
It's very light and quick to read. The book talks from the women's perspective most of the time, but is relevant to everybody.
The main point from the book for me was to be flexible and enjoy the life. Life is too short to worry or be upset.
The book is full of advices and experiences from Irina's life.
That includes how to teach kids, be public person, how to grow career as a woman, have strong and happy family and others.
The book is short and straight to the point, while it's still very personal.
