Life Goals Complete? I don't even have a life goal

 Last night, while I was desperately trying to fix my brother's broken eyeglasses, my sister suddenly asked me, "What is your goal in life?" I was stumped because 1) I did not expect that; and 2) I don't have any goal in life. And that's what I told my sister, that I don't have any concrete goal in my life. And then she ranted on how I shouldn't be like her, that right now, I should already have direction to avoid the quarter life crisis that she was experiencing. So, because of that, I now have an assignment to write (not type >.<) my life goals and let her check them (if they pass the criteria? O.o) before this year ends T_T I can't really think of something that I really really really want to do. I usually do things impulsively. And I haven't encountered anything that has captured my interest for very long. That's why this assignment is veeeeeeeeerrrrrryyyyyy hard for me :((
