Are the two of you headed in the same direction? This is what you both begin to ask yourselves after a while. In the beginning, this question probably doesn't trouble you; it doesn't even come up as an issue.
But after spending some time getting to know each other and how you each work in the world, you've started to realize that you're not exactly on the same page in terms of your work, your chosen career and the direction that your lover is heading in life. You have some very particular and well-formed goals in terms of what you need to do to reach success -- what kind of networking furthers your goals, what kind of traveling you need to do, when and where you might need to move in order to open up more opportunities for yourself, and so on. Your lover has the same idea of their own future; even if it's hazy, they have a picture of where they'll be in five or ten years, and their picture doesn't match up with yours. If you've made firm plans, they definitely aren't similar to those your lover has made, and if you're in love and committed to the relationship, you're both faced with the issue of which one of you is going to make the compromises needed to stay together. At least one of you has to slow things down in your own life if you want the relationship to work out, because you just aren't moving at the same pace. Talking things out and working together is a great approach to getting more on level ground with each other.
