I lost you when you started classifying success. There are no classes of success - its defined purely by your own drive and identified purpose in life. It maybe important for you to impact the world some how - but to someone else - success (even of the home run variety) may simply be having a successful marriage - happy kids and enough time for people they care about. Would you say Gates, Jobs, Brin and Page hit home runs - or would you the kid who came off the streets and made a decent life for himself - enough to provide for himself and his family and live comfortably - hit a home run?
