Narrative:

About 10-20 miles from the airport; I copied ATIS information which indicated wind from 190@7. This favored runway 11; so I requested and received a visual approach to runway 11. As I maneuvered to enter a right base for runway 11; the tower informed me that the winds had shifted to 220@9; and offered me runway 25. Since the winds favored runway 25; I accepted runway 25. The tower cleared me to land on runway 25; and I confirmed that clearance. This was my first time landing on a runway other than 29 at sbp; since the winds almost always favor 29. Even though I presumably confirmed runway 25 (I don't remember the tower correcting me; as they would have if I had said runway 29); I set up a left downwind entry for 29 out of habit. The 29 downwind runs near some hills; so I became preoccupied with the terrain. Turning base for 29 (not 25; as I had been cleared) I requested and received a wind check. I then turned final for 29 and landed. In the landing rollout; the tower advised me of the deviation and provided a phone number.because I was used to landing on 29; and complacent from landing on a VFR day at [this] airport; I didn't stop to think about the unusual (to me) runway assignment; or stop to double check my assigned runway. I also didn't write down the assigned runway. If; after getting the runway assignment; I had written it down and/or slowed things down a bit to allow me to focus on the unusual (to me) clearance; I'd have been much more likely to realize my error and avoid landing on the wrong runway. Instead; because I was complacent and distracted; I landed on the wrong runway.
