Wanting to write books?

I have never really been a good writer, but a dream has always been to write a book. I found the web site of the company 37Signals (www.37signals.com) and started reading their book "Getting Real". I'm not gonna comment on the book just yet. I like real book and not just reading from the web. And found Lulu (www.lulu.com). What so great about Lulu? Well everyone can publish their own book, and when somebody orders a book it is printet on demand. For me in Sweden it to about 7 days from order to delivery! Really makes you want to write one on your own.
