The decision as to when to quit, as to when one is merely floundering around and causing other people trouble, has to be made frequently in a lifetime. In youth we are taught the rather simple rule never to quit, because we are presumably following programmes made by people wiser than ourselves. My own conclusion is that when one has embarked on a course that grows increasingly doubtful and one feels the vital forces beginning to be used up, it is best to ask advice if decent advice is in range...
