My wife tells me this all the time - because I am on the spectrum I see things in black or white; work vs fun, productive vs unproductive. Only black or white. I think I'm starting to understand...
The key is moderation. Don't dedicate 100% to productive-only tasks or you'll burn out. Don't dedicate 100% to veging on the couch watching TV or you'll bore out.
Can't everyone just stop analyzing every minute detail of life and just chill by living in the moment?
