Sometime in the next week (or even the next day) when you have a conversation with someone -- listen to them fully.
Don't spend your time thinking about what YOU want to say next, or what story you want to add. Force yourself to slow down and listen to every word they say.
Reflect on their words. Think about what they've said without inserting yourself into it.
I admit that I'm guilty of listening and planning at the same time. It's not that I don't care -- I DO care, quite a lot! -- it's just that I've been talked over so many times growing up that I feel an almost desperate need to be a part of a conversation.
I think it's time I slowed down a bit. My friends aren't adults, irritated at my interruptions. They're fascinating, incredibly wonderful people, and I'll bet I get to know them better if I focus on them a little more.
What about you? Do you catch yourself spending your attention on your next response instead of listening to the person talking?
