The majority of these young teens end up on the streets, and their chances of ever being someone successful in life are greatly diminished because they will most likely never finish their education, they have a higher risk of developing drug and alcohol problems, and they may result to stealing in order to survive.
It is very difficult to be successful even with a high school diploma, and for the majority of these kids they may never finish high school because they runaway from home at such a young age. When living on the streets there is no telling what type of bad habits people will develop, and with many of these young kids suffering from depression the chances of the developing drug and alcohol problems are that much higher. The chances of these young teens resorting to theft in order to survive are much more higher with them living on the streets, and eventually they may come to trouble with the police and get sent to jail. This will just make it more difficult for them to be successful in life because it is really difficult to find a job once a person has some form of criminal background.
