Yes, you just have to get over the idea that you are
looking at "your data". Unless you are looking at
pages and pages of numbers, that's rarely ever true.
At best, you are looking at a representation of your
data on a computer screen. That representation can
be manipulated in an infinite number of ways to give
us insight into what the data means. But that is not
the same as what the data is.

Cheers,

David
