Human Factors
Departing OSH; I was cleared for takeoff off. I made the early left turnout as directed by the NOTAM for a VFR departure and began the climb to 1300' and the turn to what I thought was the correct heading as per the NOTAM. I turned to a heading of 130. It wasn't until I neared the seaplane area that I realized my error and that I should have flown a heading of 150.I did receive a pilots briefing and read my paper copy of the NOTAM. I also got ATIS prior to departure. When I began my turn to the heading of 130 I was confident I was going the correct direction. I must have misread the NOTAM.From this point forward I will reread the pertinent details of the NOTAM again to myself immediately prior to departure. A visible note of the heading and altitude would have prevented my mistake.
GA pilot reported not flying the correct heading during takeoff from OSH; realized the error and corrected to the right heading.
