Narrative:
I was cleared to descend to FL300; 30 or 40(? - Can't remember) and the clearance was amended to stop at FL360. When subsequently cleared to descend the clearance was to FL330; which I orally confirmed but mentally took as the original FL300. I descended below FL330 and was directed to turn 15 degrees to avoid conflicting with airspace reserved for another airplane. I have no explanation for why I did this other than it was just stupid - I do not recall other distractions or flight difficulties. The weather at the point of my error was not a factor.
