Who is the most productive person you know personally?

The most productive person I know is the vice principal of my school. She is one of the most productive people around me because of three reasons following. First of all, she communicates and cooperates with all teachers about every tasks of the school from administration to student care. She tries to understand every teacher\'s opinions and help their work at the working level. Secondly, she assists the principal well with a full passion. I think that she plays a good role as a bridge between the principal and the regular teachers. She understands the position of both the principal and the regular teachers and make a harmonious atmosphere. Lastly, the vice principal devotes to her duty as a mother and a wife as well. She is very good at cooking and caring her family. I think that her productivity comes from her diligence and the love for her life. I want to learn these attitudes from her.
