One of the connections that we humans have, but often forget about, is the connection we have to the divine. You may call it God, or Higher Self, or Spirit, or Guardian Angel, or something else, but that connection exists.
It's so easy, through the busyness of the day, to forget that connection. We try to cram as much into our day as possible, which means that other things miss out. Overdoing means we are being less. We forget who we really are, and why we are here.
I know I'm guilty of that on a frequent basis. I like to check things off my "to-do" list just as much as anybody, and I like that feeling I get when I complete a project (you should have heard the whooping and hollering in my house when I finished The Gemini Bond).
I think the secret is to follow the advice of the Bhagavad Gita. We need to do everything in service of our Higher Self/Spirit/God, and keep connected even when in the throes of being busy.
That's the challenge for all of us.
