Textbook...

I have been writing my own textbook for the past four years. This year, I combined two classes, and rewrote that same textbook; changing the progression of the steps as well.

When I went to search fro an image for this post, wouldn't you know that wikiHow has a post on how to complete this process. 

Now this post goes over selling the book. I disagree with that right there. These books should be a part of the course. This is how I enjoy the process. This also allows me to update as the software updates. Not sure how this will continue when I decide to retire. Will not be updating the book then!
