Jenny has reprinted parts of Leslie Burger’s inauguration speech on her site. It’s pretty “go go change!” but if you’ve ever spent any time with Leslie you’ll know that her enthusiasm is infectious.
Build a culture that encourages and rewards change. Encourage your staff to take some risks. Offer rewards for new/different ways of doing things. If they turn out be better, great! If not, recognize, appreciate and learn from the effort. Be relentless about promoting the changes you want to see. Good example: The library that encourages staff to keep track of how many times they say no and figures out how to turn no into yes.
