Is the work we're doing really beneficial?
Should we invest in more laptops or iPads?
Am I building the leadership capacity of my teachers?
Then.....I read an article in the Guardian UK about Global Education and the hope to reach ALL students in the world by 2015, and you realize there is always more work/reflection to do. It never stops, not enough hours in the day, resources to support, more parents to call, meetings to attend.
Make your 'field of impact' smaller and you'll be more effective on a daily basis. Continue to teach and lead and enjoy the day!
