Don't neglect yourself. A body that is well taken care of is much more easily able to deal with the stresses of everyday life. Eat a nutritious and well-balanced diet, exercise regularly, and get the rest your body needs. It's the advice our mothers gave us, and it still works today. When something needs to be done, just do it.

Even if you are feeling very reluctant to begin a project, once you're in motion you'll forget your initial concerns. It may help to start out with the simplest part, and ease into the most challenging. Finding a balance in your life is an ongoing process. Allow yourself the time to regularly reassess the direction in which you are heading. Patiently, but steadfastly work toward your goals.
