... I'm optimistic about that but not sure I'll be making much more money any time soon.
Tough love incoming. Dreamtime is over. Fantasyland has faded away, and you have been deposited on the cold hard shores of Adult-land. Time to wake the hell up.
Yes you will be making more money soon, and you will almost certainly not like it, but that's too damn bad. You have a grownups debt. You have borrowed other people's money and not paying it back is not even remotely an option, so you will be making more than 100/month in the near future.
You are going to have to set aside your dreams which other people have foolishly been entertaining for the past few years, and you are going to have to sell your time to other people.
Once you have established some level of work experience and credibility, you can feel free to become an entrepreneur.
In the interim, take any job that requires a breathing human being, at any wage. You are not "too good", "too educated" or "too special" to flip burgers, sweep floors or guard warehouses at night.
While you are doing these things, keep applying to firms who would employ someone with your degree. Working at the other jobs, while keeping body and soul together, you will be demonstrating many other things of value to employers: work ethic, ability to show up on time, initiative, problem solving, diligence, team work, maturity.
Once you are employed in your field, take college courses to expand your knowledge, skills and credentials. If your expensive degree is valued so little that the average salary is below the American average, then you need to bust your ass to get the credentials that people will actually pay for.
Above and beyond adopting a mustachian way of life, you NEED to increase your earning capacity. People will pay you to fill their needs. If your aspirations are aligned with meeting those needs, fantastic. But it seems that they aren't. So bust your butt to change that. I can dream of a life as a Wheel-wright all I want, but I've no-one to blame but myself when the wagons that need wheels fail to appear at my door.
You CAN repay this debt. You CAN establish a life, own a home, own a car, save for retirement, have a family if you so choose, and retire earlier than most people. But this requires you to get your head out of the clouds, roll up your sleeves and get dirty.
