One of my favourite non-fiction books is called "Think and Grow Rich" by Napoleon Hill.
Originally written back in the first major depression of the 20th century this book is the standard by which I judge or other self-help books. It's a huge bestseller and there countless numbers of versions.
In my opinion the best version is the original version restored and revised with revisions and so on by a guy called Ross Cornwell. Ross has brought the book into the 21st-century and make it readable for a modern day audience.
The main reason I like the book is that the author Napoleon Hill spent a lifetime carrying out research before publishing its findings in this book. And when you look at the people he spoke to during his research, you know that the suggestion he puts forward to improving your lot in life actually works.
I think it's further to say that the book has spawned a whole industry of self-help and how to improve your life books. Many of today's so-called gurus cite this book as one of the main influences that help them build their careers and created the lifestyles they desired.
I'm halfway through reading the book for a second time, as I read it a few years ago but didn't really apply its teachings. However something made me pick up the book again (the version I'm reading today) and start afresh.
The book is mainly about improving your bank balance and becoming wealthier but you can use it in any area of your life. For example, if you're single and looking to find a partner apply the teachings in his book and I'm pretty sure you will find that perfect someone faster than if you didn't read "Think and Grow Rich".
During what people are calling "the first great depression of the 21st-century", reading TAGR again is appropriate because it's making me focus on the things I need to do and pulling my head out of the sand.
If there's something you are struggling with in your life, I think you could do worse than read "Think and Grow Rich". It has inspired many people to great things, it's changing my view on life, maybe it could change yours.
