Doing what we love: listener question

I‘m just reading this book: The way of integrity by Martha Beck and I have a question. She talks a lot about doing what you love and this confuses me. What is this even? Probably this inner yes. But what is this? Like the teaching. Do I love this? Would say no spontaneously. Having a family, baking bread, even cleaning, do I love this? Would say yes spontaneously. Does this mean I need to stop teaching to live in integrity from my inner yes? But I don’t. Why? Just don’t know why I’m doing it and don’t know why I’m not stopping it. Totally identified. How do you understand this doing what we love?
