Writing a book (especially for SAS Press) is an incredible experience. If you are playing with the thought of doing so, I highly recommend that you proceed with this idea. You’ll get a much better structured view of your favorite topic, learn a lot about yourself, and enter a very nice user and author community.
1. Celebrate a book burning ... No, don't get me wrong! Do not burn your book after it is finished! But burn the printouts that you collected over the many months when writing the book. You will see that getting rid of all the hard copy evidence of exhausting work is very pleasant for you. It is acceptable to have one or more beers during that exercise. See an example photo of a randomly selected author in Austria, Burgenland.
2. Be relaxed! Not only because you have finished the hard work. Also be relaxed when you find the first error in the final print version of the book. If you are lucky, it is only a small typo. Other examples could include wrong references to chapters, pages, and diagrams. Experience shows that it is usually not a questions WHETHER you find a mistake, rather a question of HOW LONG IT TAKES until you see the first one. Before you start thinking about the WHY (did the copyeditor oversee it? did the reviewers not mention it?), it is your book. The glory and the faults are with you. It's like the first scratch on a new car. As soon as you have one, the second does not hurt that much. This is a good time to start the "Changes and enhancements" document for the book and publish it on sascommunity.org.
3. Take some days off, drive around a nice place, and have a very good dinner. A famous Austrian ski jumper (Toni Innauer) once said "Always enjoy the success, it will give you the power for new tasks". And I think this is very true. Don't stumble into the next project without enjoying what you have achieved. To celebrate my 2nd book, for example, I took some days off after SAS Global Forum 2012 in Orlando and drove with my new book to the coasts of Florida and had an excellent dinner at a fantastic location in the Florida Keys. As you can see from the pictures, my book was very thankful and enjoyed the experience as well.
4. Be proud when the curtain opens and you are on stage! After you have finished your book, there will be occasions where you can present your book and its ideas to the user community. This can be a presentation at a user group or any other conference. You can run webinars, open a blog or discussion forum, run a workshop or write a paper on your book. In any case, enjoy these possibilities. Seeing and talking to people who are interested in your topic is the true reward of writing a book.
I hope these suggestions also help you feel better after writing your book. Have fun!
