It's that time of year again-when you vow to shape up, lose weight, and start saving...just like you have...dozens of times before. The difference this year? These winning strategies, which studies show will enable you to make real changes in your life. Bonus stat: Scientists say it only takes 21 days for the brain to form a new habit. And just knowing that can help you conquer anything.

Resolution 1: I will go to the gym
The trick is to plan your workout schedule as seriously as you do cocktails with friends: Studies show that you're more likely to stick to a fitness plan if you set a schedule in advance. Ears peak when we mentioned cocktails? Well then you, missy, are best served by a morning workout routine, so you'll have no excuse to cancel on the gym when after-work drinks beckon. And, during your workout, listen to music that's 120 to 140 beats per minute-think "Push It" by Salt-N-Pepa. Fast, but not too fast, paced music is proven to keep you moving.

Resolution 2: I will eat less garbage
Start by clearing your cupboards of candy and cookies and chips-because you know very well that if they're in the house, they will be eaten. And when cravings hit, take a walk: A study published in the journal Appetite found that a 15-minute walk reduced the desire for even the most craved food-chocolate.

Resolution 3: I will be better with money
We know, we know-it's not easy to leave Bergdorf's without a new pair of Louboutins. But the secret to not overspending is taking 48 hours to cool off. "If you're still in love with the item after the two days and it's in your budget, then go ahead and buy it," says David Bach, author of Smart Women Finish Rich (Broadway Books). Another trick: Use cash wherever possible-you'll be surprised by how traumatic it can be to part with actual money.
