I am a Nursing Student

I had this little moment of epiphany that was encouraging a minute ago. I was standing in line at Starbucks for my grande latte, and I looked around seeing that most of the people here have money, are dressed nicely, are a "certain type" of person. Then I looked down at my new dark jeans, new brown men's dress shoes, and my new 3/4 length sleeve cream sweater (all purchased on my Student Loan credit card), and thought... "I am one of these people too."
Now this is all said very well aware of where I came from and how truly shallow these things are, yet it gave me a little boost of confidence and motivation that I badly needed after narrowly escaping a D in my Anatomy Lecture Exam a little over an hour ago. I have been so frustrated with this class. It's difficulty level is very high, and I have been treating it as just an aspect of my life instead of a main focus as it requires. My focus has gotten better and better with each low C I have received over the past two or three exams. Thankfully, I've been scoring higher in my Lab Practical Exams and those grades are holding me at a solid overall grade of 79%. One point away from a B.
 I have been struggling with the fact that at 35 years old I am making $8 an hour, and trying to remedy that by spending a lot of time on networking and building a beautiful resume. I may not be focusing where I should be. I will be making $25 to $30 an hour after getting this degree. It is highly important that I EXCEL at these classes, so as to be hand picked for the first available nursing classes. Thankfully no one will see the separate exam scores only the overall class score. Thinking about that end goal of a high wage (as shallow as that may seem) is motivating me to focus harder on my classes. I have children to provide for, to motivate, to help excel. I must focus hard and do well to provide for myself and them now, and for myself in the future when they are supporting themselves.
I am not just an $8/hr home health aide. I AM A NURSING STUDENT.
