It was not the first thought to appear twice in my mind, but it is one that I try to remind myself of.
Do not do unto yourself what you would not have others do unto you.
In particular, I try to remember it when I am tired, but fail to go to bed, imagining that a lack of sleep is rarely of significant harm. Also, when eating well past satiety. What, would be my response if someone else were to insist, or even suggest, I stay up late when I am tired, or eat more when I am no longer hungry? I can almost guarantee that I would think him foolish and annoying. For me, a critical aspect is where I perceive the locus of control. While I feel I have control, I permit myself leeway, sometimes to my detriment. If someone else appears to seek, or presume, control I often fight the suggestion, even if it might be beneficial.
This is pretty much equivalent to people saying, “Sometimes, I’m my own worst enemy.” That can go for playing music too loudly, as well.
