Taking an overly personal interest in your career or other work is a bad idea on your lover's part. It could lead to tension that ultimately damages the relationship, if you're not both careful about it from the beginning. What they think is just helpful support, good advice and a reasonable set of expectations actually comes across as meddlesome or even controlling.
Each of you needs to find your own path in life, to shape your own career and meet your own successes. Sure, they have a wealth of experience that's there to be drawn from, but that doesn't mean they should offer it unsolicited. It's much more meaningful to let you find your own way, which includes making your own mistakes. If you put too much pressure on each other to succeed in a particular way or timeframe, you could end up really resenting each other. Even if your lover knows that they have a skill you lack -- organization and planning, maybe, or diligence and motivation -- they should keep it to themselves, unless you ask them for help. Otherwise, what's supposed to be a romantic connection starts to feel like schoolwork -- drudgery, high standards that are impossible to meet and an endless requirement to succeed and impress.
