Narrative:

By allowing myself to rush to the departure runway, I misunderstood the instructions from ground control and taxied onto the active runway without a clearance to do so. Furthermore, a company aircraft had just received a takeoff clearance for full length on runway 24. I was very anxious to make a wheels up time to boston and requested an intersection departure from taxiway a. I acted on either what I wanted to hear or expected to hear and taxied into position and hold. The ground controller evidently said 'expect takeoff from runway 24 at taxiway a' and I thought he said cleared for takeoff. Cause of incident: being in a rush. To correct the situation: don't rush.
