What moment made you realize you could beat Dark Souls?

I remember being so intimidated by the game before playing it for the first time and struggling a lot with the beginning sections of the game. I remember fighting the first black knight in undead burg and thinking I would never beat it. After giving up a few times, I finally managed to kill him by blocking and then circling around. I've grown much more as a player since then, but that was definitely the moment where I knew I could overcome the challenges thrown at me. What about you guys?
