Know your subject and legislation extensively. Comprehensive as well as sound understanding of the substantive regulation is a must. Know your subject, its nuances, interpretations as well as vital instance regulations to have a command on the legislation that you are practicing. No amount of interaction or composing skills could play down the lack of understanding in legislation which originates from constant analysis and practice. Repeated reading of law with an open mind brings different connotations as well as opens the door for creative interpretations.
