How do you get through Mahler or Bruckner symphonies?

For one, I never just sit and listen. Usually I read or "do something" on the internet. That is ironic because the internet truly is wasting time. However, it
feels like I'm doing something.
It's hard to watch operas, too, because I'm married with children. I got really excited by the filmed Boulez version of the Ring (didn't like the Levine and HATE the visuals of the Barenboim), but it bored my wife to tears. I watched a nice Magic Flute, which my daughters actually joined me watching and enjoyed (they had learned about it in school). My wife sat through a really fun "Barber of Seville" with me but it was the exception that proves the rule--I haven't found another opera that moves that quickly and is as fun (and she just barely made it through that).
I've rented a couple of other opera Blu-Rays, but I had bad luck, i guess. I found the productions just terrible. One opened with a group of ninjas assassinating someone (it was
not a modern opera). It looked like it had been choreographed by a 14-year-old, and thought up by his little brother.
I made it half way through a very good Julius Caesar that came with the HMD baroque opera box, but then the family came home and I never made it back to it...
