"Plans are only good intentions unless they immediately degenerate into hard work."
This book gives you a take on how to leave your 9 to 5 in order to start a business for $100 or less, and turn it into a full time income source.
1) Having passion is important but far from enough. You also need relevant skills and paying customers.
2) In order to turn your passion into a source of income, focus on revenue and costs. Otherwise, it is a hobby which only has costs but no income.
3) The secret to success is to keep things simple and value action over extended planning.
READ IF: You are thinking about starting up on your own and want to take action now.
