UT interview

hey yall. i just got done with my interview at UT-Houston. they did away with personal interviews and now about 30 people go in at a time and do a writing sample. i feel okay about it. i mean i feel like i didnt really say what i wanted to say. we had to answer 3 questions. one of them was about how i plan to ensure success during the program (e.g. educational, financial, personal). for financial, i put that i have completed and submitted my financial aid application and that i also plan on getting a job this summer at a doctor's office to help with future financial responsibilities. i told my mom about what i wrote and when i told her that she was like "why didnt you mention your family?! blah blah." im just worried now b/c i feel that my answer for the financial part is stupid... and im worried about it now. what do you think of my response? is it dumb? be honest please..thanks
