I counseled many returning missionaries. I interviewed 1,700 missionaries all over the world. My advice to them is that you should study and prepare for your life's work in a field that you enjoy.
It is easier to give directions than advice, and more agreeable to have the right to act, even in a limited sphere, than the privilege to talk at large.
Although this garrulity of advising is born with us, I confess that life is rather a subject of wonder, than of didactics. So muchfate, so much irresistible dictation from temperament and unknown inspiration enter into it, that we doubt we can say anything out of our own experience whereby to help each other.
