at what a age were you "successful"?
"Successful" is certainly a relative term. I successfully started my first business and turned a profit at age 20. Successfully graduated from IU at 22. I was successfully married at 22. Successfully had my first child at 25 (at least my wife did but I was involved). There are a few more but these stand out in my mind as most important. I've also certainly had my share of failures which I consider ammunition that helps me to be more successful by making better decisions moving forward.
