I have no way of knowing whether I'd be interested in your book since I don't know what your qualifications are (e.g., how much programming experience you have, have you studied the psychology literature related to procrastination, etc.) or how well you write.
One way to figure out if people are interested in your writing is to blog about your topic and see if your blog gets a lot of visitors and commenters. Then you can use your blog posts as the basis for a book. For example, Michael Lopp's books grew out of his blog - see http://randsinrepose.com/books.
