For me being successful means being successful in all aspects of life- financial, relational as well as being prosperous in health. 

Succes according to me in his simpliest and original meaning is to discover the reason for your existence and achieve it before you die  (your dreams your life goals and define your priorities and their deadline   ...)

For me success is to have a good relationships with your closest people, a good job, do what you like, find your purpose and your place in the world, have enough money for not thinking about them constantly, have your own house, have peace and calm in your soul. And what is success for you?
