The trick: Take the money you save on little things each week and put it away until the last day of the year.
Sarah on "Discipline":
Just like weight loss, there is a certain, unequivocal math to saving: fewer dollars out than in.
There's no fudging the math; you just have to be disciplined. With temptation to spend everywhere, sticking to your plan is easier said than done.
One of the most effective techniques for staying on track is to visualize the prize. Whether you will use the extra $500 toward paying off some debt, investing in a CD or in your 401(k), or toward a winter trip to Disney World with your kids, if you can keep your eye on the prize, it helps with discipline.
So make a goal poster, hang it in a high-traffic area at home and track your progress every day or week. You'll soon see how your daily choices make a difference. It also doesn't hurt to get the whole family involved - especially your spouse.
Alicia on "Ditch Perfection":
Being realistic, you will occasionally slip up - and that's OK. It's hard to change habits.
Knowing this, it's important to think ahead and develop tricks for getting back on track quickly if you have a moment of weakness. We recommend a healthy dose of forgiveness followed by one or two significant steps to help you recommit to your plan.
If you don't forgive yourself for slip-ups, you're actually more likely to throw your hands up, call yourself a failure and keep on over-spending.
Bad spending habits may not be easily broken overnight, but if you make room for imperfection, your chances of reaching your goal and developing positive, long-term habits are significantly better.
If you're having trouble getting your budget in order, here are three tips to help you save about $500.
Go homemade - How often do you eat out? Even if you just buy coffee or lunch, it is amazing how quickly ordering out adds up. Making coffee at home instead of buying it every day will save you $40 to $50 just in December - more if you order expensive lattes or other fancy drinks.
Brown-bagging it can cut your daily lunch tab in half. If you spend $5 to $8 for lunch, over four weeks, you can save $50 to $80.
Dinners out also add up. If a family of four eats out, it might cost $50 at an average restaurant. If you can make a meal for four with around $15, you are saving $35 per week. That's $140 in December. Total savings on food service: $230 to $270.
Go generic - Buying generic instead of name-brand foods at the grocery store can save you about $75 to $100 per month.
Shop like it's 1975 - Remember layaway? Instead of paying 13 percent to 20 percent interest on the $1,000 worth of holiday gifts this year, use layaway. You can pay little by little up ahead of time instead of paying a lot extra in January. Money saved (on $1,000 of gifts): $130 to $200.
