If your lover is dissatisfied with their career or with what they contribute to the world, you try to help them to find a better way to be an effective part of things -- but any advice you give could fall on deaf ears. You just might not grasp what it is that your lover wants to do; you might completely misinterpret or undervalue their talents, and could give advice that doesn't even apply. This doesn't have to be such a bad thing, though.
In fact, it might end up being a positive experience, because it forces each of you to take responsibility for your own work and for being an effective and content member of society. As long as you don't expect to see eye to eye on every little thing, you're probably okay. And hey -- disagreeing on outward subjects like work and social obligations is a lot better than disagreeing on more personal, intimate matters, right? If you give it time -- and plenty of clear, conscious communication -- you even come to a point where you do understand each other and the talents you each possess, and you have a better idea of how to help each other be more effective in your work.
