Would You Be Missed??

Seth Godin wrote a great blog asking the question whether or not companies or people would be missed.  If Target went out of business, would it be missed or would you just go to a similar store? What about Pizza Hut? With so many options and easy replacements, are there that many stores that would truly be missed for a long time?  The same goes for people in companies and jobs.  I want to be someone who will be missed, someone who made the place I was better to the extent that I’m not easily replaceable.  I want to be that specialty lightbulb rather than the regular.  What are you doing today that will make you missed?
