If the work, and by that I mean devoted personal practice, not going to class and nodding knowingly at your teacher's words, does not come natural – if you don't find yourself aching to dig in when you wake up in the morning – then the chances are that you are not karmically ready for the work. Such students, in the old days, would have been set to work in the monastery garden or kitchens, or, if Christian, would have been directed to spend a few years working at a hospice or almshouse. Nowadays however most students aren't even ready for that.
