There are many reasons to write and publish. Many writers will suggest magnanimous reasons, high and mighty reasons. There are plenty of selfish reasons to do so as well, nothing wrong with that.
I will suggest one selfish reason here.
Have a kid tell you they checked out your book from the library.
That’s an incredible reason to write and publish.
For those that don’t know, I teach. I teach first grade. Yes, men, from time to time teach the younger grades, but that’s another post.
My school announced yesterday that my book was now available to be checked out from the library. I had students ask if they could check it out. I reminded them they already had a class copy and that others should be able to read it if they wanted to.
When going to lunch, a student from another class told me they had checked out my book. That is a cool feeling, no way to describe it.
If you are teacher write your book, and then see what I am talking about.
Go do it now.
