What really matters? Now, and ultimately? How do you know what you think you know is so? When are you qualified to pass on your wisdom to others? When does your experience become worth something of value to somebody else?
Everybody has "their" own answers to those questions, as the vast expanse of the cyber world alone demonstrates. We're all consumers of others' answers online and otherwise. Whose is the little voice in our head that tells us to listen to these experts? How does it know the experts are reliable, or more important, right, as in "correct?" Why do most of us largely live on intellectual autopilot, and trust almost everything we hear and see?
Some of us try not to. Some of us apply a frame of reference to our "garbage in" port.
