Sometimes we push ourselves physically and mentally to help others. If it is something that really makes a difference in their quality of Life than it is worth it. But to push yourself doing things for others that really doesn't matter at all is definitely not worth it. You have to put your own health and time in making your quality of life better. If you run yourself ragged you won't be able to help those around you if they really need you. Be kind to others but don't be foolish.
