I'm still waiting to be changed, but I did read I'm Okay, You're Okay when it came out in 1969 and it definitely made me begin to think of different ways I might approach problems or hurdles in my life. I've never revisited it and would likely find it laughable now, but heck, I was 17 at the time. ;)

Still an instructional book on interactional psychology. I wrote a paper in Grad school in the early eighties on transactional psychology vs Gestalt theory and used that book as one of my primary sources.

Walden Pond..... You don't own the cow, the cow owns you. Less is more.
The other one was also "I'm OK, Your OK." [Do you remember the board game Cop Out?]

Living free in an unfree world by Harry Browne. Atlas Shrrugged is a close second.

The Magic of Believing by Claude Bristol.

'The Late Great Planet Earth' by Hal Linsey

I've never gotten over Old Yeller.

From an educational standpoint, I learned a lot from The Wall and Exodus.

I thought "I'm OK, You're OK" was an interesting book when I first read it.
Over 40 years later, I still find still find transactional analysis helpful in understanding behavior.

I was influenced by Wayne Dyer's Many Lives, Many masters. Very impressive book. And also, Beatty Eady's Embraced by the Light. That book brought much consolation after mom's passing.

I find it interesting that this book, affected so many. To live in the villages you have to be pretty comfortable leaving others behind. Hopefully they are comfortable letting you go. I wonder if I'm OK, Your OK has something to do with both of those decisions.

Your the last person to mention the book so i posted here. the discussion is open to anyone.

"Who moved my cheese?" Helped me through a few big changes in my life.

. Probably "Grace and Grit" by Ken Wilber although most of it was taken from notes written by his beloved dying wife. It touches everyone who reads it.

The China Study by Colin Campbell Ph.D.
 

His life's work was in nutrition and he proved that animal protein promotes cancer. Cancer was my main concern because everyone in my family had it. After reading his book I became a vegan to help avoid getting cancer.

Becoming a vegan was a big change in my life and now I feel a lot more hopeful about my future. Cancer doesn't seem like a big threat anymore.

Oh, one more, "Leisureville" by Andrew Blechman. Had I not read it I probably never would have heard of The Villages.

Most of us have read many, many books. I believe my life has been influenced by great numbers of books, and regrettably I can't single out just one to add to this great thread topic.

How can I count all the books that stirred my life long passion for reading and further reading? How can I make a workable list and then narrow it down to one? I'm a relgious man, but to just blurt out The Bible would be very inaccurate. Biographies, autobiographies, travelogues, novels of all sorts, histories, and so on and so on.

They all have in ways affected my life, some in big ways, some in unnoticeable ways. And without any offense or smart alec attitude toward BarryRX ( who stands tall among the posters here) I am sure others feel as I do.
