Though individually you might focus on your dreams and ideals for the future, together, you'll have a restrictive, inhibitive effect on each other's ability to attain those ideals. Whenever you have a bright, creative, high-flying idea about a goal that you want to meet, your pal will tend to bring it down with an overly sober explanation of everything that might go wrong. And whenever they're trying to be serious about working hard toward one of their goals, you'll be off somewhere, refusing to focus or get serious with them.
Neither of you deserves to have your sense of responsibility challenged or your joie de vivre stripped away. So your task in this friendship will be to learn how to move forward and achieve your goals, even in the face of a challenge from this friend. It might not be a fun process, but it could be a very important step in developing your own strength and determination.
