"Sheepish shoemaker"
"Cordonnier mal chaussé"...
Can anyone relate to that French expression? Tonight, I totally feel like one of those people.

The proverbial "sheepish shoemaker" is a skilled individual who neglects to leverage their skills for their own advantage or advancement.
I have a perfect example - a story of predictable irony:
I just emailed a client suggesting they start using and assigning hashtags to all their conference and customer event planning. It's definitely a good idea. Hashtags remain a powerful social leaning tool used extensively in higher education circles. And in my industry, they represent an untapped, strategic resource for finding and engaging medical audiences.
After I sent the email, I checked my personal Twitter feed. Apparently, I've been too busy to use hashtags this year.
It's a little too late for me to recall that email. But it's never too late to start hash tagging more consistently. One simply needs a defined purpose.
Does anyone else have a sheepish shoemaker story?
