Narrative:

I was practicing instrument approaches to gfl; ILS runway 1. My first approach went missed. On my second approach; I was able to land and do a touch and go. I misunderstood the instructions from the TRACON - evidently they wanted me to follow the published missed procedure. However; this assumes that one is still at the missed approach height; and not on the ground. I therefore decided to use the instrument departure procedure instead. However; in my haste of trying to review it in flight; I misread it. I read to climb to 2;500 feet straight ahead; instead of a climbing right turn to 2;500 feet back to the if/MM on the approach. I did have terrain warning which showed I was >1000 feet above the terrain; and there were no terrain conflicts. In the future; when planning such a flight; I should have the departure procedure memorized and not attempt to read it in flight.
