Forking duck

Who is the speaker and what is she referring to?

...it's all great fun, then you get halfway through and you think, "What the hell have I agreed to do, it's too hard, too stressful." And then you get over that and it's fine, and then you absolutely love it for a couple of weeks, and then you start thinking, "Oh my God, is this ever going to end?" and then you realise it's not going to end and you have to make the best of every night. And then you start to learn again, and you do that for a little while, and then you go back to thinking, "When will this fucking be over?" and then you get to the place where you're like, "Oh my God, it's going to be over soon, and this is such a wonderful experience!"' She forks in some duck salad.
