one of the best pieces of advice i ever got as a newbie (and i was an A student), was to always respond to calls for help, or trouble, any type of need (I'm on L&D), because that is where you will learn. and I guarantee you that stuck with me and helped. and to this day i offer help. not only was i putting myself out there for things that may be difficult/uncomfortable or "not my job" (as some people would say), but i always learned and it helped me later on. or, if enough people were there i could walk away but know what should happen if i was ever in that scenario.
