How would you define success?

Most people would define success as being rich, driving luxury cars and living a lavish lifestyle. However I strongly disagree with that. As a son of immigrant parents. My Dad came to this country about 3 decades ago. Worked 2 jobs to bring my mom, siblings and me to America. My parents raised 4 children into successful adults. They also managed to build a business and 2 huge houses in Africa, where they will retire to. I would also define that as success.
