Have realistic expectations of people and programs. There are only 24 hours in a day, and we do have to sleep sometime. Make sure that those you hire to lead technological changes are competent, and that you are clear as to what you want them to accomplish. Set up contingency plans to fall back on. Know that change is a painful process and be ready for the bumps in the road to success.
People come before technology.
Take a step back from things every once in a while to view the overall picture. Don't take yourself too seriously. Don't expect others to become responsible for things they have no way of delivering. Acknowledge people for their good work on a regular basis. Hire technologically capable teachers.
