You actually are able to help this partner be successful in their work or their public life, because of your own dedication to hard work. You're very productive in your own work and career, and you have a lot to offer them in terms of support, guidance and motivation to further their own career. You help them to be patient, instead of acting rashly; you help them to become a more reliable person, as you impress them with the idea that reliability is an important quality in a business partner or whatever they might be.
You have a traditional view of the best way to achieve success; you believe in hard work and perseverance first and foremost, and you also believe in treating your clients or customers with the utmost respect. Your lover sees these qualities and values within you and they take them as inspiration for their own life and work. You also tend to be realistic in your goal-setting, and you're able to help your lover figure out exactly what they can and can't reasonably accomplish. If you help them brainstorm for their work, you're able to help them fine-tune their business plan, as well as their plans for their general, long-term future. Actively motivating each other in these areas is very beneficial to both of you.
