Sit up straight.
I'm sure we've all heard this command from some authoritative parental figure at one time or another.
Changing one's posture takes only attention and will. I go through periods where my posture deteriorates and I spend a few weeks being aware of the times I'm slouching, and pushing back my shoulders in response.
Changing the way one walks isn't quite as simple, nor is the process discreet.
When I walk, I don't lift my feet much. I don't drag my feet and I don't shuffle, conversely, I don't glide or sashay. There's nothing remarkable about the way I walk.
Except that every once in a while I trip on absolutely nothing. I don't fall, but I lurch rather noticeably.
I recently had the (not so) brilliant idea that I would change the way I walked the way one improves posture.
Have you ever thought about the way you walk and tried to walk differently? It's not an impossible task...for a distance of about 50 feet, but it's not sustainable.
Visualize, if you will, the sight of me walking down the halls of the psychiatric hospital where I work, picking my feet up in a slightly exaggerated fashion...somewhat the way someone walks when their foot has fallen asleep. Now, adjust your mental picture when you hear that I walk like a cross-dresser when I wear heels.
I decided that vanity is worth the price of the occasional stumble, and all efforts to change the way I walk are a thing of the past.
...and sit up straight.
