How to shift dreams into goals?

For the last few months I’ve been enjoying the idea of “possibility”. My husband and I talk about our dreams in general terms like how we’d love to travel internationally with the kids, how we’d love to get a bigger house with more bathrooms, how someday I’d like to be a life coach and public speaker. I’d like to shift these dreams into goals, with measurable steps, but I’m having a difficult time, largely because I don’t yet know HOW we can accomplish them at this time because many of the things require money that we don’t currently have. I feel like we have an abundance mindset, and I truly don’t feel like we are lacking—it’s just that these next level of dreams are more than what we have now. How do I begin to accomplish goals I haven’t figured out how to fund just yet?
