I wandered into a nearby cafe at about two in the afternoon. They were just catching their breath. They had run out of something I wanted, so I asked for something quick. When it came out, it looked a little small.
I've come to realize that if I feel a bit of disappointment at the size of the portion I was served, then that's actually a REALLY GOOD sign.
It means it's enough and I will finish without wasting anything. More often than not, it's even slightly too much.
If I'm served and it feels like enough, then it will be too much.
If I'm served and I think, "holy crap, that's huge," then it's WAY too much.
I've learned to recalibrate the brain with the gut.
