"The most important thing to remember about any practical book is that it can never solve the practical problems with which it is concerned. **A theoretical book can solve its own problems. But a practical problem can only be solved by action itself**. When your practical problem is how to earn a living, a book on how to make friends and influence people cannot solve it, though it may suggest things to do. Nothing short of the doing solves the problem. It is solved only by earning a living."
