I think what you say about perseverance is always the most important thing. We tend to give up on things when they don't go the way we want them to, but we shouldn't decide. In our case, our child likes us to read stories to him, and he's always with his books for us to read to. Sometimes we find him reading (or pretending to read) to his younger brother, and it's an impulse that we want to take advantage of.
