Mr Money Mustache sets some pretty low standards for himself but he advocates some sound concepts, I would suggest reading: http://www.amazon.co.uk/The-Millionaire-Fastlane-Lifetime-eb...

Advocates better practice (yet similar) and in 5 years.

"the most important message in the book is that business and entrepreneurship is the path to success, NOT being an employee and staying in the rat race."

The best book that I have read that emphasizes this point is "The Millionaire Fastlane" — awesome, awesome read ... a must for anyone starting, running, or thinking about creating a business.
