House/career or uncertainty/adventure?

I'm having trouble commiting to my dreams. It's not that I won't commit at some point, it's just that I don't feel it's the right time. Like Christopher Cross said "if the wind is right, you can sail away, find a better place". I want to live in different parts of the world, I don't want to stay in one place. Although, I can appreciate that one day I will have a family and that will likely keep me in a place I can call home. The trouble is that the longer I stay, the smaller the gap becomes to settle down. The sooner I leave, the wider the gap becomes to settle down. My ambition to have a family means that I must plant my roots deep which takes time. I'm afraid that if I leave too soon, I could jeopardise that. All being said, I'm a risk taker and love nothing more to cut the rope and make the leap.
