Are you complete?
You’ll know if you’re not. There will be something niggling on your mind, something that keeps you awake at night. Or an uncomfortable sensation in the body.
We will never get everything done, complete, as there will always be something else.
But what you can do is have everything handled. An outstanding job written down at a specific time to complete in the diary. Something you did or said that you regret, scheduled to put right. A promises that you made and broke, or know that you will have to break, with something in existence to clean it up.
One minute you will feel complete, and the next you notice something that isn’t. If its not practical to get it complete right now, schedule the completion so that its handled, and your mind and body is freed up again, to enjoy the present, or be creative.
