You know what else adults do? Read the writing on the wall. They stay home until they can afford to branch out. They get roommates. They do what they can to keep body and soul together, instead of going off half cocked.
You say you shouldn't be barred from growing and exploring because your income isn't in tune with the area. You can grow and explore with a roommate. You can grow and explore within your means.
I seriously want to know what lies you told on the application for your apartment to get it. Either they were desperate to rent that out with no credit or income check, or you lied.
