Somehow, you'll both know that a long-term friendship will be advantageous in some appreciable, perhaps material way. You may share similar values and goals, and you'll both know you can work together toward them, as a team. That's all well and good, but the trouble here might be that in the face of all those long-range goals and material ambitions, you'll have a hard time simply having a good time with each other.
Take care not to neglect the fun side of your connection, because with this aspect between you, you might both tend toward a sober interaction indeed. You could also unknowingly send out signals to your friend that they should curb their creativity; they might grow to think that you'll disapprove of their efforts.
