A very small decision I make on many mornings is which coffee cup is going to be mine and which goes to my partner.
The two cups we normally use are the same and I cannot tell one from the other. If I thought one was better than the other, I would give it to her.
What happens is at some point while I take the cups from the cupboard and set them on the counter, I incline toward deciding that one of them will be for me and one for her. This “decision” is so small I describe it as “incline toward deciding.”
As I continue preparing morning coffee, my very small decision about which cup is mine spends more time in my mind. By the time I pour the coffee, I am generally always mildly set on which one is going to be mine for the morning and which hers.
My initial “inclining toward deciding” has changed into my being “mildly set on” which cup is mine. I might even feel a bit possessive toward “my” cup as I pour the coffee.
The main point is that once we make even a very weak decision or incline toward a weak decision it requires energy to change that.
Of course, I do not really care which cup I get and yet I have inclined toward one or decided on one of them. At some point in this process you have to do that.
If I try to change my decision once the coffee is poured and give “my” cup to my partner, I am aware of expending a bit of energy.
The energy required to change which cup is mine is greater than the energy required to decide which cup is mine. I only fell into my initial decision but must climb out of it if I want to change it.
I bet you do this or something like it, too. Just watch yourself and observe it happening. Once you see it, try changing to the other cup or whatever it is you have chosen.
It’s not hard to change your decision but it decidedly requires a little bit of energy. That may be some of the smallest mental energy you will ever exert, but you will have to exert it.
I find I feel a bit awkward when I change my initial decision. It seems my mind is already set at some lower level so the meta-level that changes that does not have the right networking or connections for the transition to be completely smooth. This is the opposite of the initial decision which seems to have required little or no energy. And has managed to grow bigger all on its own, outside of my awareness.
Notice also, if you are like me, you will happily give your partner the better cup if one of them is better. That decision, too, will require energy to change, maybe even more energy than if the cups are the same. This probably happens because if you change your decision to the better cup (for yourself), you will also feel a bit selfish in addition to the above considerations. This will happen even if your partner wants you to change cups.
So either way—changing between two cups that are the same or changing from the worse cup to the better one—you will need to expend a bit of energy, even though your initial decision probably required none at all.
