Probably the greatest benefit of any 40 day practice is that you do the practice for the 40 consecutive days. Then there's the benefit of the chosen meditations.
If you look at what you're most consistent at in your day to day, you'll get a clue as to why things may or may not be working for you in each specific area. Because we get really good at what we do (or don't do)! And that's good news, because we can change that.
Think a marble can roll off the deeply embedded groove and take an unpaved path that doesn't exist... without any interference?
It would take some fingers, or a disruption in its foundation to lift or shake it off its current path.
We're the same way. We've been hitting that snooze button every day for so long that expecting ourselves NOT to extend that arm to hit snooze and fall back asleep would take some dedication and honest desire to make change.
That's just the beginning of the morning...
