A few things to try, if you haven't, besides formal sitting meditation:
Walking meditation. Can be done any time one finds oneself walking. Just note how each foot touches the ground.
Jed's "spiritual autolysis", his journalling on steroids. The instruction is, "Write down something true". Write a statement that appears to be true, then question the assumptions behind it (maps, models in your words) and question those. Repeat until the truth is arrived at.
Or his twist on the Mindfulness of Death exercise (which can be combined with the jounalling approach): "Why shouldn't I kill myself right now?". It's certainly powerful, but there are also less potentionally damaging approaches.
Other things to try throughout the day (not necessarily from Jed's books):
Pretend you're watching yourself doing stuff, commenting on it mentally, whenever you can remind yourself. "Watch Florian taking a shower". "Watch him close his notebook computer". "Watch him open a door".
Keep a meditation word or mantra running during the day. Resume whenever you remember.
Or keep track of the breath during the day, whenever you can remember.
All of this can be fuelled by Jed's suggestion: "Further!".
To get back to your original post: I got a lot out of reading Jed's books. I once remarked that if I hadn't come across MCTB (Daniel Ingram's book) first, then the Jed books would have been my all time favorite modern enlightenment books.
Cheers,
