As others have indicated, this is a book that addresses the psychological aspects of being self-employed as a small business owner or solo practitioner. definitely one of the best business books on the market that offers honest and "real world" advice despite being written several years ago.
highly recommended reading for anyone thinking about starting a business - but especially for lifestyle entrepreneurs. the book refers to these type of entrepreneurs as being "propreneurs." the authors were ahead of their time as more and more entrepreneurs are starting businesses and choosing self-employment for lifestyle (as opposed to strickly monetary) reasons.
