Motivates me? I have a wife. I have a dog. I want a house and children next. Those things are the greatest motivators a man can have in my opinion. Oh, and killing neo-nazi punk aholes whenever they appear.
Knowing that they are due and if I dont make money to pay them, ill be harrassed by collectors. Getting ahead makes me feel good and I know I can relax again, but when it catches up, there I go banging away at the computer again.
