Best piece of advice I could give to anyone is make as much relevant connections as possible and preserve them as best as you can. Jump on every connection possibility as fast and as enthusiastically as you can or just hook in to existing connections between existing connections.
I always viewed wearing multiple hats as proving your worth. Hey look, I can do my job AND others AND do a damn fine job at it all. Personal internal cred.

Do the job that's in front of you. Exigencies of the service and all that. If it's way out of the pale, then it's good for later anecdotes and additional experience. At Nike my cubicle name tag always got flipped to Batman when I was out running calls, I thought that was droll.
