I'm going to ignore what my mom wants
Why would you ignore you mom's wants?
I studied so hard doing what she wanted me to do. It's my turn now to decide for myself.
It is good you studied so hard, your parents want the best for you. You should still be mindful of your parents and not ignore them.
Why should I bother doing what she says when she's just another normal person?
But she's not, she is your mother and she just wants the best for you. You can always listen to her and still do you own thing, but you shouldn't just ignore her.
