Not literally, but bear with me. I don't like listening to the radio, so my daily commute to work/clients is filled with podcasts (I'll do a separate post on that in the future).
One of my favourite podcasts is Back to Work. I love listening to Merlin Mann and Dan Benjamin. They talk about A LOT in less than 2 hours per show. And from time to time, there's stuff that just sticks in my mind.
"I'm always right" came up in a story by Merlin. If I recall correctly, he taught his daughter how to remember whose glass she was holding in which hand, by thinking about that line.
So next time you pick up two glasses, you know where to hold yours.
