A study done by Scranton University found that only 19% of people keep their resolution for two years, with 30% giving up before January ends. A psychotherapist explains tips to creating a manageable resolution that will be both motivating for you and beneficial to you. One common mistake is making your goal non-measurable, such as saying “I will eat healthier” rather than “I will eat two more servings of greens a day.” Another tip is to keep your goal realistic. Saying you will save $100 to $300 a month is more attainable compared to saying you will save exactly $200 every month.
