I am enthralled by the look at the historic mind, and am amazed by the ability of science to both confirm and quantify some of our best intuitions.
We've known for a long time that how we say something matters just as much as what we are actually saying. Turns out, we are at the technological level now that we can electronically quantify how someone is feeling based on their word choice in social media. More importantly, though, we need to pay attention to the words our companions are using, and listen to what they are communicating with their word choices.
The biggest takeaway for me is that I can affect the way I feel, affect my outlook and attitude and interpretation of reality, by intentionally selecting different language. I shape my own reality - to one degree or another, one way or another.
