This aspect brings both beneficial and challenging influences to your relationship. On the plus side, you'll have a stabilizing effect on each other's thought processes. When you're together you'll think more rationally than you would on your own, and you'll be able to make more well-thought-out decisions.
You'll plan well for the future and you'll make disciplined decisions regarding your finances and other ventures you tackle together. But on the more challenging side, that mental stability and practical way of thinking can easily turn into rigidity. You'll have a way of influencing each other to be rather restricted in your ideas, and if you're together long-term, you might both become less and less able to think outside the box or take intellectual risks and leaps. If you do make a long-term commitment, you'll need to challenge yourselves consciously and frequently to think on your toes and come up with creative new ideas. Don't allow yourselves to settle into mental ruts or allow fear of the unknown to govern your decisions.
