I really like the photo I included in this blog because it's a visual representation of what I'm trying to say here. You pick up a handful of sand. They pretty much all look the same. You zoom in on a few of those grains of sand. You can see they are a little different, in color, in shape, etc. You zoom in even further. Now you can see how colorful and unique and different every grain is, and wonder how you could have ever thought them to look the same. Zoom back out...and there is just a handful of sand again. Obviously it's a little different with humans, since we are fluid creatures and what we do effects other people and ourselves, mentally and physically. That doesn't really happen with sand, though sand has the advantage of staying itself and not dying. But you get my point.
Now think about how much is going on in one single second of time. We don't often do that. Think about exactly what is happening other places in the world, or even 10 feet away. So MUCH is going on that it's just baffling to consider. The biggest part of it is that we can't SEE what is going on. It is almost all invisible. Someone's thoughts, whether about groceries or suicide or that guy from the coffee shop, etc., are the gears that are turning time itself (which could lead me into talking about how time isn't linear, but we'll save that for another day). Pretty crazy, right?
