Here's a tip, and an exercise: Change the ring tone on your cell phone. (Hey, that's cool: It rhymes!)*
I recently changed my ring tone. The first day, I missed calls. I missed calls all day long.** I heard the sound, but it didn't register. I historically have the ringer turned off 90 percent of the time. Yet, my mind is still conditioned to the old, familiar sound. I've become Pavlov's dog.
That ain't good. Don't walk around with your brain on automatic. Think again. Change the ring tone.
*This is when my mother would say, Little things amuse little minds.
** No. It didn't matter. At all.
