Each of you is an individual with some important ambitions regarding the important work that you do or want to do. Whether this is to be a professional career, volunteer work or even something like preaching in a church or teaching swimming lessons to children, you each have a calling that you want to pursue. Your relationship with your lover actually helps you pursue your goals, even if you're on two completely different career tracks.
You talk about your ambitions with them more and more as the relationship progresses, and almost without noticing it, you start to lean on them in that way -- trusting in the advice they give you and always wanting to hear their perspective on any problems or opportunities that come up. They're your advocate and self-appointed representative; at parties, they talk up your work, and whenever they encounter someone that they think could be good for you in a professional sphere, they even do networking for you -- they get that phone number or email address for you to add to your professional address book for present or future use. You're really a creative team together, and as long as you make sure to motivate each other in pursuing your life's most important work, you really derive a lot of great benefits from this relationship.
