Hello Hanna !!
If you get a music degree it needs to be with an Education minor so you can get a teaching certificate.
You get a pension and benifits as a school music teacher. Continued good behavior is an absolute must,
no drinking and driving problems to prevent you from moving into teaching.
You might also consider a two year degree in Nursing. You could get an LPN degree, then the healthcare field opens up for you. Continue playing music and work on getting an RN if you want more money.
Or you could become a certified medical billing specialist in about 6 months. Or a Paralegal in about a year. I would continue playing and singing no matter what.
As far as modeling goes, you need to join a gynm with a bunch of Nautalus machines and use the machines with NO weight on them or maybe 10 pounds, so you dont damage your tendons or knees ect.
Do more repetition rather than more weight!!
Easy to hurt yourself with the machines with weight on them..but if you use them carefully.. you get tremendous results !!!!
Gym is a must for modeling.
Many guys at the gym will try to act like they are trying to help you and get you to lift heavier weights, but it simply wont work..you are there to look sleek not like a lady weight lifter!! And besides you do not want to have an injury.
The biggest problem with modeling is that someone might claim to have a "modeling" job..but it is really a job as a call girl. You DO NOT want to go there !!!!!!!!! Or any adult modeling ..NO..NO..NO..never!
I listened to your Youtube songs and thought you have a lot of potential in music..You kind of sound like Stevie Nicks from Fleetwood Mac. Pop music is a possibility.
So I would decide how long of a education you want, look for free college grants and job training to pay for the school.
Get a potential career set up, keep playing music and then go music full time when you have at least 6 month to one year career training..LPN..Paralegal..Medical billing..Keep playing music while in school.
