"Millionaires are serious students of a successful life, not just ﬁnancial success. They continually look for new ways of thinking and acting that can produce more fulﬁllment in their lives."
Please rephrase the hilighted sentence above as I was not able to understand what the writer is trying to say. Just write the sentence in a plain way to make it easy for me to understand.
Put in very simple words, that sentence means: Millionaries are always looking for ways to succeed in life, not only to be rich.
