Please Help Me Title Essays on Estimation

I have finished the content for Essays on Estimation. But, I need a new title. The book is more than loosely coupled essays. It reads like a real book, with progression and everything.

I have a number of ideas. They are (in no particular order):

1. Predicting the Unpredictable: Essays on Estimating Project Costs and Dates
2. Essays on Estimation: Pragmatic Approaches for Estimating Cost and Schedule
3. How Much Will This Project Cost or When Will it be Done? Essays on Estimation
4. Essays on Estimation: How to Predict When Your Project Will be Done
5. Pragmatic Estimation: How to Create and Update Schedule or Cost Estimates
6. Practical Approaches to Estimation: Create and Update Your Prediction Without Losing Your Hair
7. Essays on Estimation: Practical Approaches for Schedule and Cost Estimates

Do you like any of these ideas? Have a better idea? I would like a title that explains what’s in the book.

I numbered these so you could respond easily in the comments with the number, if you like. Or, you can type out the entire title or a new title. I am open to ideas.

Thank you in advance.
