This is my right hand. On my wrist, about a year ago, I had this tattoo done. It's a rest (a musical notation symbol for silence), and from my perspective it's a whole rest (four beats of silence), but from someone else's person's perspective--unless my hand is raised--it's a half rest (two beats of silence). It serves as a reminder to myself that 1) everybody talks too much, but! 2) I should talk less and listen more. Every time I pull out Carnegie's book, How to Win Friends and Influence People, it reinforces this ideal.
"Most people trying to win others to their way of thinking do too much talking themselves. Let the other people talk themselves out."
I'm bad at this. That's why I got the tattoo (that, and I noodle way too much). But, according to Carnegie, it's the only way to connect. We've got to be comfortable with the discomfort of not saying what we think when someone else is speaking or else we will never be able to understand them. And if we can't understand them, they will never in a million years bother trying to understand us.
It sucks because, for the most part, everybody has brilliant ideas that they want to share. The problem is that listening to somebody else's [what could be perceived as lame or "wrong" or whatever] perspective puts our egos in this weird position of feeling denied. The ego cries out! But, if we are sensitive and remind ourselves that our ego is generally wrong, we can get that inner voice to calm down, start listening, learn something, and gain some influence in the process.
I'm still trying. I over-speak a lot, and it's kind of annoying I know, but with books like this one I'm reminded that it's usually not necessary, and you'll gain a lot more than you'll ever realize just by listening.
