I think they should come up with a new name for the category "inspirational" books, because from what I've seen, the only thing these books inspire you to do is to go buy another "inspirational" book almost identical to the one you just finished reading.
The authors of these dreadful tomes recycle old ideas by switching to fashionable buzz words and even twisting the definitions of time-honored concepts, then stringing them in endlessly emotional loops, all of which are open to your own interpretation, like horoscope entries in the daily newspaper.
There's no end to them, and no end to thinking about them; you might as well be a Buddhist monk sitting on a rock in the Himalayas.
Even a "get-rich-quick" book can get you off your ass quicker than an "inspirational" book.
I'm sure there must be good books in this category, and I'm partial to Buddhism myself, but most of these self-help offerings sound like lowbrow Zen and assume that you have all the time in the world to find yourself, or to discover the meaning of life or the source of the universe.
Life, after all, means what you make it mean.
So, if "inspiration" is not making you happy, try "motivation."
