The other day I started a calculation of how many connections in my brain will either become obsolete or have to be renewed, but after 245,469,478,123 I lost count. As a matter of fact, max appeared in my dreams, which hadn't happen for more then 10 years. This points to switching to 5 being a dramatic crisis indeed. I figured that viewing 5 as something non-related to previous versions of max (it might as well come from a different company) makes it easier to accept it's differentness. What appears as fixed reality is merely a shadow. This is not a piece of good advice, but simply my experience.
