The premise of this book is to design organically (No grand plans).

Programming is reduced to the sequence

• write a test
• write code that passes the test
• clean up that code (remove any duplication)

Much of the book is about getting into and keeping a good programming mindset - one nice tip is to always leave a failing test at the end of the day (this give you something concrete to start on the next day).

This book has changed the way I work (a bit).
