Tech has its place in that, though. Removing tech doesn't put you in the present moment (although it can help), but rather living in the present moment is a state of mind, just being aware of what is going on around you. You can do that while listening to music, reading, sitting and staring out over a landscape, or even watching TV... as your present moment is whatever you're experiencing at that time. Bask in it. Enjoy it. Don't worry about what you have or haven't done. That's the key, I find. Now, whether that's strictly what people mean by "being in the moment", meh.

To me it just means not worrying about the past or future, which I very much experience when immersed in a good book or film etc.
