An opportunity comes from = (passion+skill) + (problem+marketplace).
Written by Chris Guillebeau , "The $100 StartUp" is going to help you to reinvest the way you make a living, do what you love, and create a new future.
What I noted from this book you can take away is that when you want to start a business, you need to know 3 things:
1. A product or service
2. A group of people who are willing to pay for your product or service
3. A way to get the payment
With these 3 key points, in order to succeed, you need to provide the real value to your customers.
