Many of the things I write about in this Blog are behaviors my second supervisor in my career taught me. He's moved on to other places. But, on my 25th anniversary at the company where I worked, I emailed him to thank him for the leadership skills he taught me that I am still using today.
As a leader, work hard to make a lasting impact. Help create a little of you in each of your promising employees who will lead after you have moved on. They will surely be eternally grateful.
