What would I do with an English degree?

I want to use an English degree to become an English teacher. I know that i still have a long way to go as far as composition goes. I want to use it so that i can better my self and help better others. I really want to be that guy who is confident in what he writes, knowing that because of his schooling he is able to write 99% error free.. An English degree will not only help me reach the goal of becoming a teacher, but it will also help support my family which i plan on having :).
