Crew resource management means making use of all of the resources available to you, it's basic stuff, your resources are your inputs, your limits, your crew input, your use of all of these things. If at one point you begin to throw things out you think you can't use only to find out that item could have prevented the error chain from breaking.
Simply put, listen, assimilate, have the foresight to admit it is a two pilot airplane not a one man show. Those days are long gone.
Peace.
