<human>: Can you provide a brief overview of the text?

My girlfriend has been a lot of fun and the relationship is kind of new, I suppose I'm trying to get a second opinion on if I am just being crazy or what.  So this is my first serious relationship, we got pretty serious pretty quick.  As I am getting to know her more she seems to have very little overall motivation for achieving anything post high school.  

She talks as if she is very pessimistic about her future and how she will probably be working in her shitty fast food job for her whole life like her sister.  She doesn't have her license and I try to encourage her to start managing her life and achieving things but it always ends up in a fight.  It feels like she is sabotaging her own life and no matter how I try to help her she just doesn't want any part of bettering herself.  

I am a highly motivated 20 year old college student who is majoring in a science field while working 20+ hours a week.  I just want to share myself with someone who also has ambitions and plans.  She is graduating high school this summer after she makes up some credits she missed.  She also comes from a very rough past, I don't get into it too deeply for her privacy sake but it's worth noting.  Sorry I can't go any deeper than that.  

Any advice?
