It isn't worth reading tbh, i would just say it just has a fascinating outer cover quoting "Japanese Secret To a Long and Happy Life" so, it is just very well marketed because every body wants to life a happy life. But the content inside is extremely redundant. And if you are receptive of things, you would understand that the authors are trying to be sophisticated or philosophical, i said "trying to be" and that "trying to be", like i said if you are receptive, can be felt very easily.
So, i would just say, i felt it fake and showy. Thanks.
