Analyzing like an Analyzer

I just read an article in commarts.com about Singing like a Singer, by Wendy Richmond, a visual designer and writer, about how she attempted to sing along with one of her favorite songs like she was actually a singer, and she learned things that had never before occurred to her, in the many times prior, listening to this song.

I find that any time you try to change your perspective, you learn new things.  If you are upset with a room mate, sibling, spouse, or co-worker, but then genuinely try to see things from their point of view, you learn a little bit of how their brain works. You learn their motivations and desires.

The more you learn, the more varied your perspective is. It's like "the cow principle" in Econ:

Once you see the cow you will always see the cow (your perspective is changed forever).

Now you can choose to ignore it, and look at what looks like a fence behind the cow once you have seen it, but you know the cow is there.
Similarly with advertising, once you know the principle you can't help but look at commercials and think, "they're using this principle."  One example for me is fast food logos. Many of them are red due to color theory: red psychologically and subconsciously makes people hungrier.
Or with statistics, once you learn basic principles you become more wary of ambiguous statistics.
Or with music once you know what a final cadence sounds like you are apt to notice when it is used.

Basically this principle applies to every aspect of life.  Perspective is everything!
