To set goals and achieve them, start by choosing a specific and realistic goal, such as "I want to lose 15 pounds in a month." Then divide your goal into several sub-goals, such as exercising for 30 minutes a day and eating 3 servings of fruits and vegetables daily. Make sure you write down your goals and read them at least once a day to stay focused. In addition, celebrate every little victory as you work to reach your goal, for example, saying no to a delicious but oily piece of pizza. Learn more about planning obstacles for more tips.
