One of my very good buds is 5'6", Asian, and flying for SW. This is going to sound harsh but if you are over 18 who cares what your parents think. I know its easier if they provided the funds but if you are passionate about this then there are plenty of ways to do it alone. Why don't you try this.

1. Go to school and have them pay for it. You'll need the degree anyway.
2. Use whatever means necessary to obtain funds to get your ratings. You could work, use scholarships, loans, the military (my personal favorite ) or sell the Lexus !
3. Graduate and have your ratings. Now the big bucks start rolling in

Good luck and welcome aboard.
