Hello Richard,
It's good to have you on board. You've probarbly had a look around, so you can see we're a nice bunch. Welcome to the forum. Hopefully, we'll see and hear much more from you in the future.
So, you say you're burned out~ I would glean from your post, that you are simply moving on to the next stage. I have known burned out in the past and it'd debilitating and depressing. You however, seem to exude a passion and a need to pass on your skills.
I'll check out your book
All the very best for the future
