Well first of all not arguing with anything the society says then the following:
Attend every single meeting - even if you are dying and going to give the flu to everyone else, Always go out on field service, answer at every meeting not just a monotonous reading of the paragraph, you have to give a long detailed answer pref quoting scriptures, give your self up for every thing that is offered to you including cleaning the mens loos, study for every meeting, pre study your prestudy and if you have done that, read the watchtower and maybe listen to some kingdom melodies. You shouldnt have much more time for anything else but if you do, maybe apply a bit more study time.
