I've dedicated an entire year to reading inspirational/new-age/metaphysical/self-help books when I was homeschooled and what I've discovered is this.
1. People have conflicting opinions.
2. There's not enough time to read them all.
3. Reading/Owning a book on x subject does not make you an expert on x subject.
4. Doing what a book actually says is more important than reading the book.
5. Some knowledge is better off just not being known.
Seriously... I'm talking everything from tony robbins, napoleon hill, dale carnegie, eckhart tolle, dalai lama, david burns, robert green, malcolm gladwell, mihály csíkszentmihályi.
I've spent so much time reading "inspirational books" but at the end of it I've realized that the only way to get results is by doing and not reading. I'm not saying reading is bad but to get results from any sort of inspirational book you NEED to do and practice what it tells you.
I just thought I'd include that cause I think it's important to avoid the "inspirational books will solve my problems" trap. I've fallen into it before and the end result was just overanalysis of far too many different philosophies from to many different people.
