The brain is a powerful and complex organ although some people refer to it as the muscle of thinking. It won’t be ignored for any extended period of time. What’s troubling you will continually resurface until you do something about it. Once you work towards resolution on whatever is bothering you, it’s interesting how that thought seems to fade into the background. Rest almost always follows progress. I have no grand illusions that I will ever be an 8 hour sleeper. I am fine with that. I’ve had some wonderful late night/early morning moments. I just want to make sure I separate the experiences that are the natural course of aging and personal biology from those that are my conscious or subconscious mind pushing me to pay attention and take action. I encourage you to do the same.
