I've been doing meditating lately and this "be in the moment" thing is what I have a problem with. Seems to me if I try to be in the moment it's like watching cars go past--each moment goes by and is in the past and then another is coming up ahead. How can you ever be in the moment--it's illogical.
A few years ago, I was in the Rocky Mountains with a friend and we went along this trail above a winding gorge. We went along this narrow path okay, but going back there was a point in the path that was so narrow that I couldn't walk on. I was paralyzed with fear of losing my footing and falling to my death. I was thinking I might have to stay right there for hours while my friend went and got a rescue team. Finally I decided to try scampering up the sheer face of the rocks, crawling up to a place where I could stand up and walk away from the gorge and then around to meet my friend further on.
In all that experience, I never felt in the moment. To go along that path, I had to look ahead and anticipate where I was going. If I stayed in the moment, I would have fallen onto the rocks below and died. It's not being in the moment that helps us survive. You have to think about where you're going and how to get there, use your past experience to inform your choices, come up with different scenarios to follow. That's reality. Anyone who says they are in the moment is lying (to themselves at the very least)--the human body doesn't work that way. The only time you're in the moment is when you're dead--but then you're not a you anymore, because you don't exist.
The people who write the books do it for the money. In the book I'm using, the writer keeps talking about all the seminars he gives--and I imagine those are expensive. There's no such thing as a free lunch.
