If you want something inspirational, try
"Think & Grow Rich" by Napoleon Hill.
It's not about financial riches per se either.
Here are some other suggestions
"Chicken Soup for the Soul" (series of books, a little too feel-good for my tastes but very positive, very easy reading)
"Everything I Needed to Know I Learned in Kindergarten (ditto)
An author named Brian Swimme has some books that are very enlightening & postive but more intellectual and deeper reading (grab any of them)
There are also two VERY good periodicals (both published quarterly)
- Parabola (
Parabola Magazine - Current Issue) - a series of essays, articles, stories & such about positive personal growth
- What is Enlightenment? (wwwi.wie.org) -* The title says it all.* It's their 30'th anniversary edition now - very good.
