This may sound hokey, but positive thinking makes all the difference in the world as to whether or not you are a part of that 30% who sticks to their resolution. How events occur for you is a reflection of what you think and believe. If you think exercising is too hard or boring, and that drinking a lot water is like taking medicine, then most likely you will give up before the 31st.
Keep in mind the benefits of why you are making these changes. Instead of dreading water, know that you are flushing out toxins and bringing more clarity throughout the day. Or focus on that feeling of accomplishment, renewed energy and natural high you get when you are done with your workout.
When you are in that positive state of mind, you are also more apt to find solutions to things you may find cumbersome. Put some lemon, lime or grapefruit juice in that water to combat the "medicine" reaction. Find a class that you enjoy---like Zumba, pole dancing, wrestling or squash---so that you look forward to attending and doesnâ€™t feel like working out.
