Glad to read that the first thing you post in your update is a job related theme. It does reassure that you have done a terrible DB my friend ;-)
Just choose what makes you happier D, if it´s about freedom to teach and you haven´t got any offer...it´s up to you and you´ll be doing well whatever your choice.
You are a DB master D, keep that road.
My best wishes go with you dear brother. Keep on that terrible DB coming!
