Mature man

Sometimes I hear or see things that force me to confront my principles in life and I have to confess that I hate them. It simply means that I am in trouble or something is wrong in my life. Today, I heard a quote from Wilhelm Stekel, a famous psychologist:

The mark of the immature man is that he wants to die nobly for a cause, while the mark of the mature man is that he wants to live humbly for one.

Since hearing it, I have been thinking about it. I am not even sure whether I agree with him or not. This "Ology" thing is the source of my problems I guess.
