If you want to make this year a great year and have basically been setting the same resolutions each year, perhaps it's time to do something a bit different. Instead of focusing on a resolution, focus on developing the right habits.
One of the reasons why many people give up on their goals is because of disappointments, they don't get the results they were expecting fast enough. This could be due to a lot of things such as an unrealistic timeline or circumstances not within their control. If you instead focus on developing habits that will lead to the accomplishment of your goals, the results will be completely under your control. You'll either follow through or you won't. The beauty of it all is that once the habits are developed, it'll just be matter of time before you reach your goals.
For example, instead of setting the goal of losing 50 pounds, focus on developing the habits of exercise and proper diet. When those habits are a part of your everyday life, not only will it become easier as time goes by, you'll also keep the weight off as well. This is the power of habits, whether good or bad, the actions are near automatic.
If you can align those habitual actions towards an outcome that you want, slowly but surely, your life will change.
So drop the resolutions and pick up some good habits.
