@ze "Dedicated rest on purpose" as you put it is normative. And essential.

Unless substances also play a part in your story, then addiction seems unlikely given that the opposite of addiction is not sobriety, but meaning and purpose. Of which you appear to have.

On the other hand, it's easy for deeply technical people to become obsessive. Learning how to sit until your mind is quiet such that thought no longer runs the show is a superpower worth acquiring. It has been for me.

Just my 2c.
