Narrative:

After getting my new clearance, I called ground and asked for runway 32 and was cleared to taxi and was told I could use runway 36 which I accepted. I continued to taxi and somewhere in my mind's mess I went back to my original thought of runway 32 and taxied across the intersection of runway 36. Reality set in fast when controller said I had taxied across not only the runway I was supposed to use, but also an active runway. I was told to hold my position between runways 32 and 36 and that the supervisor was being contacted. After takeoff, I was given a phone number to call when I landed, which I did and told my story to the supervisor. I should have used better judgement in my decision to keep taxiing my aircraft. In the future, I will not only make sure that I fully understand where I am and where I am going, but also make sure that my passenger leave their problems at home.
