According to my Chinese fortune cookie, he who always does his best, his best will better grow. These are powerful words, as they remind me off all the opportunities we are presented with each day to become the best that we can be. What we need to realize is this requires both feedback AND a willingness to change.
Food for Thought:
Be still and listen
Be receptive of critical feedback from colleagues and administrators
Try to collaborate on a daily basis with grade level colleagues to share ideas
