Narrative:

Turned on wrong taxiway after hearing and briefing the correct taxi-out instructions. I was very tired and had just flown the same trip the day before, and what I expected and had done previously for the taxi out was different this time -- not what was issued. There was no conflict at any time, and we notified ground control when we recognized our mistake -- no problems thereafter. Also, first officer had head down programming the FMC on my taxi out, he should (and I should have told him) have been hands out for the taxi out. All the lessons were learned -- enough said! Factors were fatigue, habit patterns, and situational awareness.
