How to incorporate law and primary education in a personal statement?

basically i wanna apply to both teacher training and law, but do not know how to put both into a statement... and basically have already changed my mind twice now .. so cannot do it again for a third time to just one subject so need a lot of help!

Just say you enjoy a position of authority, critical thinking. Say what skills you have good problem solving, work experience. How the subjects you are studying at the moment are specific to the courses you would like to study.
