Your lover's whole approach to life brings a big boost to your career. Just the way that they naturally deal with people and the world in general teaches you a lot about how you want to behave in your business affairs. They have a natural charm with people they've only just met, and you watch them talk to people and you start to mimic their methods.
Whatever it is that they're interested in helps you move forward in your career. They're probably into a lot of things that you do professionally, only for them, it's a hobby. If you get involved with each other romantically, you can expect to spend a lot of time talking about those hobbies and about your position in society. They motivate you to get bigger and go higher than you might have thought you could before you met them. They open you up to the possibilities available to you, and it isn't even difficult for them, because they're just being themselves, and that in itself is inspiration for you! They get something out of this influence as well; you help them to focus their ideas and bring them to fruition. You might even decide to work together on some sort of business venture, because you both realize that you're a formidable team.
