What is a good field to go into for a middle class life?

my name is brandon i am going into my senior year in high school and i would like to know what i could do to make myself a decent life. I am a hard worker and could do labor but i am unsure of it. I am the kicker for my schools football team and i run middle distance for track and have some success but could you help me find a place were i would belong. I am great at math and chemistry but bad at english and history.
