Meditation on Body Energy and Its Correlation to Behavior

Ok, so, backstory: I am tall, a young adult, and I eat lots of food. My moods and behavior are definitely affected by how much energy and the type of nutrients that were in the food I ate within the past 2-3 hours. I dislike being drained of energy, so I try to conserve it. I view many things by the energy I expend to perform the tasks, and as a result, my thinking goes like this: I have this much ____ energy at the moment. Is what I am about to do worth this ____ amount of energy? If not, I do not pursue the action; if yes, I do. It seems kinda silly at first, but I think if things were viewed on an energy/calorie basis, things might be different.

For example, say, I am stuck in a horrible traffic jam. I can sit there, curse, and honk my horn at others, but that is an inefficient use of energy from the food I ate a few hours ago. It would be more efficient for me to sit there and enjoy the time listening to the radio, talking to my passengers, or observing the view. Regarding obligations, they are just that, I find it efficient to fulfill my obligations and be done with them; I find it to not be worth my energy to complain about them.

Just another piece of my mind! It is my way of logic-ing out negative feelings: it just ain't worth my energy, and it ain't efficient.

Does anyone else think like this or similarly?

Not at all the discussion I anticipated from the title .
I don't generally put very much thought into how much effort a task requires versus how much energy I have to invest in it in quite the way you describe. If I am seriously planning something out, such as a permaculture design, then I will try to include all sorts of things in my calculus, including how much work (energy) a task requires. Given multiple ways of accomplishing the same goals within a design, the one with the lowest work threshold is a likely winner. As you say, it's a matter of efficiency.

How I handle being stuck in traffic depends more upon my general mood than anything else, but when I am able to think rationally I choose to relax and try to enjoy whatever is there to enjoy, rather than fretting over something beyond my control. Sometimes I may be wound too tight by other circumstances for me to be able to relax, stuck in traffic unable to get to that critical appointment, for example.

And on a day to day basis, just doing whatever around the house - I almost never think about it in terms of energy cost. It is all just stuff that needs to be done whether or not I am up for it.

Every other creature has instinctual strategies to conserve energy. We have to think about it . Ironically , we have spent millennia inventing labor saving devices to save ourselves from back breaking toil. Now we sit at a computer in an ergonomically designed chair with our endocrine systems in a full bore fight or flight state. Good job David for taking control of the brake handle at an early age.
