I read very little in the self-help or self-improvement genre, but this book was given to me expressly by a friend at work who said it had helped him and thought it might be useful for me, so I read it.
I very much agree with the main them of the book, which is that we can accomplish much more in life, gain more enjoyment, and bring more enjoyment to those around us by being the type of person who thinks of ways to make ideas successful rather than jumping first to all the reasons why we think something won't work.
I always have in my mind that book written about successful people always suffer from a survivorship bias — people who try and fail at something are much less likely to write a book about it. Any several parts of the book are directly about implementing big ideas and starting business, etc. I don't have any desire to start a business, but the author also put in plenty of ways to apply possibility thinking to the more mundane aspects of life and relationships.
Overall I found the book to have good ideas that I hope to be able to implement in my life, and the author's style is engaging. The author's big success was in establishment a very large and successful church in southern California in which he was the main preacher. So he ties in a lot of references to scripture and the teachings of Jesus from the Bible. I appreciated this aspect of the book and found that it was helpful for me in contextualizing the ideas as I am also a religious man.
