while learning my way around Git, trying to understand what's what and where i am

HEAD is where you're at → where your HEAD is at, that's where you are. Like...if your mind is here, you're present in the moment. If you're not where the head is, you're everywhere, but here, in the Main. And if you're not in the Main, where he Head is, it's hard to experience the coolness of life in the present.
