I revise my books every so often.  I try to do it yearly.  I enjoy rereading them and usually find a place or two that needs a touch-up.  But I was in the shower this morning thinking about really rewriting a couple of books– completely rewriting them from scratch.  Specifically my first two books Princess of Amathar and His Robot Girlfriend would be very different if I wrote them today.  I think I’ve learned a lot about story telling and writing in the past seven years.  So I think I’m going to do it.  But not now.  I think I’ll do it just after I retire from teaching.  That’s still six or seven years from now.  I have too much writing to do between now and then.  Besides, think how much more I will have learned in the next seven years.
