A workable and effective way to meet and overcome difficulties is to take on someone else's problems. It is a strange fact but you can often handle two difficulties-your own and somebody else's-better than you can handle your own alone. That truth is based on a subtle law of self-giving or outgoingness whereby you develop a self-strengthening in the process.
