a permanent learning process

I remember once my MO told me during my HO(house officer ) time, in a process of learning procedure , see one, do one and teach one. Even when i am a MO in GH , my consultant also tell me the same time but when i worked in teaching Hospital, my HO don't show initiative to learn procedure ( about 90% of HO population), they more interested go back early then do procedure. It is very sad for current Ho population and worrying . I wondered how do they cope with the procedure when they are MO.
Ask specialist to do? I am not sure.
3days ago, A great teacher of medicine, Prof Izham came to our ward to give his teaching. His enthusiasm towards medical knowledge, advancesu in medicine other than his speciaty really impressing. He said even when you subspecialist in medicine, you should well aware of other internal medicine development, after all . YOU are the physician at base . A physician should always learn the new thing.
The moral of the story, medical field is a permanent learning process even for great professor .Then why our HO show no interest to learn?
