Keep your room tidy. Because otherwise women are going to constantly nag you about it when you get older. Other than that I suppose you could try and argue back at her when she says you're a failure you could list your acheivements (Topping the state for japanese is pretty big, and holding down 2 jobs as well as scoring so high)

Just sounds a bit like your mother is taking out her frustration on you. What's her life like?
