It may imply that, if staying in your comfort zone makes you happy. Everyone comes with a different outlook on life. For some it's important to create startups. For some it's important to have a stable income, pension, benefits, etc. There is no universal truth as to what one should do in life to be "successful". I have a feeling that if Mother Teresa and Warren Buffett were transposed that each would be unhappy.

What is important is to find out what balance of friends, family, work, charity, money makes you happiest.
