After a while, you start to notice that there's some tension between you regarding the work that each of you does -- or doesn't do. You're used to working hard in a disciplined way, and you could get annoyed by your lover's tendency to be more carefree and undirected about their work. They're a spontaneous soul with a healthy dose of enthusiasm for life -- which could get on your nerves if you have even one drop of envy about their high-flying disposition.
You could feel restricted by their responsibilities, and this person represents the freedom you wish you had. If you start noticing the friction that comes up as a result of this, you both have to take steps to resolve it. You, the more responsible and dutiful partner, need to try to remember that these are choices you've made in your life. You could choose to drop everything and become carefree and spontaneous too -- but that isn't you, is it? At least not all the time. But you could borrow some of your lover's spontaneity, sometimes. And they could use their good humor to get you out from behind that desk and outside into the world. You can help each other to both work and play harder, if you just try to understand where the other is coming from.
