I've read it a few times. However I must confess I've never truly implemented the lessons or suggestions long-term and whole heartedly. Nevertheless I find it to (inspiring) in the sense that espouses the belief that one's way of thinking effects their outer life.
When we change our thoughts our circumstances change.
Mastering the ability to control one's thoughts when the media and everyone around is attempting to gain mindshare from you is a feat in itself. I've also observed in myself as well as others that very few people are willing to "put their all" into anything.
As in eat, drink, and sleep their goal day and night. Most people will make half-hearted efforts and if they don't see any fruit from it they give up or move onto the next dream.
All one needs to do is read several biographies of successful people and you'll see a reoccurring theme of overcoming rejection, obstacles, and failures that took place (before) they broke through. Very few of us utilize the "Mastermind group" technique or daily/nightly affirmations. Just like diets we'll try them for a short while and then go back to what is comfortable.
It's been said Edison had 10,000 failures before finding the right filament for the light bulb, Coronel Sander's recipe was rejected over 1000 times before KFC was launched and Soichiro Honda's life story reads like a real life Horatio Alger story. Walt Disney went bankrupt and the list goes on and on.
Awhile back I heard a motivational speaker say; "There is a major difference between having a dream and when the dream has you."
I'm also a fan of Neville Goddard books especially;
"Feeling is the Secret"
