This month has 5 weeks in it. That means if you get paid every other week or even every week, you will get paid an extra pay check this month! Try to save at least half if not all of that paycheck.
You won't even know you're missing it. You could also use that extra money to take a fun weekend vacation or make an extra payment towards your credit cards, mortage, or other bills.
I'll be using mine to pay off a medical bill and the other half will be put into savings.
