This is a silly question, if you think about it very hard. Of course it’s okay to be average. Most people are average. That’s the definition of average.
For some reason, our culture can tell us that we need to be special and better than average. But not everyone can be better than average, because that’s not how average works.
If I hire a contractor to come work with them, chances are that they will be average and they will do an average job.
If I got to a restaurant, chances are that it will be average and I will get average food.
And that’s okay! If we want to improve together, we don’t need to beat the average. We just need to improve what average is.
