When the time comes, young men, make your career choices. Know that whether one is a neurosurgeon, forest ranger, mechanic, farmer, or teacher is a matter of preference not of principle. While those career choices are clearly very important, these do not mark your real career path. Instead, brethren, you are sojourning sons of God who have been invited to take the path that leads home. There, morticians will find theirs is not the only occupation to become obsolete. But the capacity to work and work wisely will never become obsolete. And neither will the ability to learn.
-Elder Neal A. Maxwell, "Put Your Shoulder to the Wheel," April 1998 General Conference
