The point here is that you always know exactly what you want. The question is, do you have the ovaries to admit it? If you can't be honest with yourself about what truly matters to you, you can't be doing what's really right for you. I'm not saying you have to act on every whim. I'm saying you need to honor your passion for anything that evokes it, and act accordingly. Never allow anyone to make you be less than you are.
