Ineed some motivation to me not quit school. lol.

I think being at social study category the quetion can be ok.

Quitting school is one of the worst decision a person can make. Why is that? Let's see. More knolegde a person have, more possibilities to take good decisions. School help us to evolve as a person, to improve our brain capacity, to develop qualities, to fight with deffects, to socialize.
Maybe you won't became a succesfull person, but if you are smart now and finished your school, after that you'll be smarter.
You can change yourself in time and maybe you'll want to finish school but you have to work to support family so... Take advantage of your age

The best sociological research method would have to be using experiments although it has some disadvantages as well
