Do you regularly move outside your comfort zone, trying to expand it over time? You should, because widening your comfort zone and ignoring others while learning accelerates your growth.
If you take any dance class regularly, you'll notice this interesting thing about people: Most claim a certain location in the class as their own. After being in a class a few times, there is some comfort to setting up in the same relative floor space.
The regulars end up mindlessly dancing/exercising in the same location, in almost every class, unless someone new gets "our spot" before we arrive. They just don't know they have claimed our spot, but they'll learn. Some people get downright indignant if you move into "their" normal location. You'd think they were paying rent or they owned the space, like the fabled parking spot with your name on it. You'll see some people showing up earlier than normal, just to lay claim to their comfort location.
If someone stands in the front, they almost always stand there. If they hang out in the back, on the left side or close to the door, you'll see them there regularly. The same people set up camp around the instructor every class. We're creatures of habit and you'll observe this behavior in almost all recurring classes.
In jazz or ballet classes, if you go "across the floor" (a series of spins/turning exercises, with two or three people starting every 8 or 16 counts), once the order for going across is established, it's an unwritten rule that the order stays that way for the rest of the class.
In other words, if I'm first in my line, I will be first for every new exercise specified by the instructor. People who violate this unwritten rule are looked down on by others in the class. And most people who go second, in the middle or last, do so class after class. They get comfortable with being in the middle or at the end.
For your maximum personal growth, you want to vary your position in the class. Seeing the routines from different angles provides additional input for your brain to process, and it pushes your growth. Try the class on the right side a while, then switch to the left of the instructor. Going across the floor first or last puts a different pressure on you if you've been hanging around in the middle zone. Up close next to the instructor is a very different feel than hanging around in the back corner. Take note of your comfort location, and move to a new spot every few classes.
In some classes I'm very uncomfortable in the front, but I make sure I go there occasionally as part of my "Dance like Nobody's Watching" exercises. I'm forced to focus on myself, my refinements, and getting over worrying about what others think. Sometimes it's a major stretch for me, but over time, the results are worth it. Moving to a new location toughens you because you have to ignore those around you, who may be more or less advanced. They really don't care about me or you, or think about us that much, because they are there working on themselves. And if they really want to watch me (not likely), they could see me in the mirrors while I'm in my standard, comfortable spot anyway.
Staying in the same place may provide mental comfort for me, but it isn't the best way to learn and grow. If you attend a class regularly, avoid getting stuck in a rut and standing in the same location each class. Try moving around the room to different positions--you'll see that it changes your perspective. Get next to the instructor in some classes, and change sides in others. If you do this regularly, you'll improve faster, have more fun, and find new perspectives on some existing materials, making you a stronger dancer in less time.
The man who is too old to learn was probably always too old to learn.
