Dear Roth,
You can’t be more right to want to live your life the way you want to. However, in order for you to pursue your dream, it seems like you will have to earn it. If it comes down to dollars and cents, you may be able to save faster by spending less or lower your standard of living…there is a cost to freedom. From what you have said it seems like your father will not let you live there and have your freedom.
It is a big step to forego financial security for your dream. Good luck to you.
