Human Factors
Tired after four days and should have called out fatigued but I decided to push on. It was a very simple taxi clearance; Bravo to Quebec to hold short of 34C. In my mind after taxiing onto Bravo it would be the next right turn; when in fact it was the second turn. After realizing what I had done; it was too late to continue on Bravo. ATC advised us of the mistake and told us to continue on Papa to hold short of 34C. ATC then cleared us to cross 34C to Tango to Quebec to get us back to the end of 34C.
