Query: THE most practical book I have ever read

I didn't buy this book through Amazon, but I loved it so much that I had to review it.A very practical book that was written with lots of examples by a very experienced person. I found it extreemly useful in setting up my own database consulting business. it contains things such as:How to price your time, how to choose your client, how to ensure that your client has confidence in you, pitfalls to avoid when building your business etc.Excelent!
