I need ideas to answer the following question: "Describe the link between your status as an adult learner and your decision to enter graduate school."
At the heart of this question is why someone who has already lived some adult life and is finished with college now wants to attend graduate school. Before answering these kinds of questions, it's often helpful to consider why the question is being asked. In this case, the college may want to determine how serious applicants are and therefore how likely to finish what they begin. Perhaps they're using this question to get a writing sample, assuming that writing about one's self is most likely to be the most accurate writing one can do. Or maybe they want you to actually think through your reasons and be able to articulate them. In any case, the question must be answered. So start with this: why, at this stage of my life and career, do I want to attend graduate school?
The "link" referred to in the question will probably have one of two components: need or want. You either need or want to continue your education. If this is already clear to you, it's easy to write from either position. "I need to continue my education because..." or "I want to continue my studies because...." The difficult position is probably one of relative indifference--"I don't have any other plan right now, so...."
This is not a trick question; the college (presumably) wants to know how what you're doing now connects to your desire for graduate study. Write honestly and effectively, have at least one other person read your work for errors, and send it off. Hope that helps. Best wishes on this new adventure.
