To me, being successful means...
Finding joy each day in something: be it an action I perform, an interaction with family, friends, colleagues, an experience in nature or a story I hear. Joy is a deep happiness that comes from within which is what makes life meaningful and keeps me grounded despite external conditions. Being happy with what I have, where I am in life and career. I do not base my success on comparisons with others.
My definition of success has changed over time.
I now know that success is internal. It is not defined by my outward conditions and materialistic trappings but who I am as a person and a member of society. Success is my own view of fulfilling the destiny life has laid out for me by being true to my beliefs.
