Narrative:

Previous night, there had been a lodging mix-up, and it took longer than usual to get to bed, although day is my official rest period. On the third day of charted freight for another company (whose plane was down), picked up IFR clearance to psc from geg. Taxi instructions were to runway 21 to end, or 'F,' my choice. Read back instructions that I would be taxiing to taxiway F. After run-up at taxiway F, tower cleared me to take off runway 21. Pulled out on runway and turned right instead of left, and departed runway 3. Just after liftoff, realized my mistake and notified tower. Tower said 'no problem,' and gave me new on course heading. Learned that situational awareness only takes a second to lose, and that being well rested for every flight is important -- even if you have had your official duty rest period.
