Do Non-Farm Payrolls Scare You?

Last night I put on a short USD/JPY trade. Most traders wouldn't put on a trade hours before Non-Farm Payroll. However, the market is going to go where it's going to go. Obviously right now I am still holding onto that trade and ANYTHING could happen. However, I know that my methods put the expectancy in my favor. So why wouldn't I trade before NFP?
