How to want a goal

Recently, I have noticed I am indulging in the feeling of confusion. I have a few goals I would like to work towards and reach, however when I start to think about those goals, my brain questions if I really want them. As I question if I really want them, my brain says, see you can’t make an obvious decision of yes, so you really don’t want them that badly, and it’s just going to be a waste of time trying to get there. I then try to come up with other goals I may want and I cannot think of anything. I end up getting nothing accomplished and I feel down on myself for keeping the status quo. How do I stick to a goal and delineate a clear game plan without being persuaded by my brain that my goal isn’t good enough?
