Narrative:

Assigned 7000 ft leveloff at 8000 ft. Single pilot operation, center gave a frequency change at the time, got busy and missed the altitude alert. It was a short flight and this was the return flight. Earlier flight had been at 8000 ft. Center called for assigned altitude just as I saw the error. Went back down to 7000 ft. These things happen and I don't think anything will stop it. People being as they are, try to be as diligent as possible, but even the best of us make mistakes. For myself I try to learn from them and improve. The best way is to slow down and not do anything during the climb and leveloff, but fly the aircraft. On short trips of less than 100 mi at speeds of 250 KTS or better, things can happen fast and those are where you have to be at your best.
