There may be some outward differences between you that have to do with your work or the level of recognition or success that you've reached, or even in your ages or your levels of life experience. Maybe you're far apart in age, or maybe you're already well-established in your career while your partner is only just starting out. Despite these outward differences, on the inside, you're very similar.
Recognition and success are very important to both of you, and neither of you is a stranger to hard work. You both recognize the fact that in order to get anywhere in life, you have to apply yourself in the best way that you know how, and to take any great advice that you're lucky enough to receive along the way. You, especially, take a similar approach to your relationships. You're grounded and practical in your work, but also in your love affairs; you take a realistic approach to matters of the heart, and you don't tend to let yourself get swept away on a cloud of sensation and romanticism. Because of that fact, you two do very well together in a relationship. You're both looking for the same things -- someone who is as hardworking as you are, someone who wants to put the same effort into the relationship as you are to ensure that it's a success. Once you make that commitment, you're in it for the long haul.
