You shine in brainstorms, negotiations, and turnarounds — anywhere fresh thinking beats procedure. Repetitive maintenance work will drain you fast.
You excel in supportive, detail-oriented roles — healthcare, education, administration. You need a respectful environment that values your quiet contributions.
You're a fun, stimulating partner who keeps the relationship intellectually alive. You need someone who enjoys sparring with you but will also call time-out when play turns into poking.
You're tender, loyal, and deeply committed — love expressed in a thousand small acts. Let your partner in on your own needs; vulnerability is not a burden.
