I think that the answer is different for everyone. Some might say being rich makes you successful, some might say being beautiful. My dad always told me that the relationships you have with people are all you really have in this world. I think when you die, you don't take your possessions with you (obviously), but the lives of the people who you've touched are made richer because of you. So I think a successful life comes around when you've had positive relationships with others, and they with you.
