I agree, but I will add you are not outright born with these qualities - look at all the successful people (we have Richard Branson as your Bill gates) and they were all driven hard by their parents without which I doubt they would be where they are today. I would say they certainly have the predisposition to become succesful but I bet there are 100,000 Bill Gates or Branson's in the world for each generation that never amount to anything. It is known many very bright and capable individuals live a desperate poor-mans life.
There are also some very rich idiots that prove you do not need to be a cut above the rest to appear successful in life. We have Alan Sugar, who even admits himself he got very lucky - I am not sure but Donald Trump strikes me as someone who was born in the right womb.
Parenting is a heck of a lot more than driving your kids though, it is about bringing them up in a well adjusted environment amongst many other subtle things and as I am finding now is a balance you are always fighting to get right!
BTW I am not in anyway bitter about people born into money or privileged environments, in fact I have a heck of a lot of respect for people like Bill Gates - more than most people it seems. I just see that people who say you entirely make your own life are normally talking from a pedestal and haven't been (or started) as low as some of the people who never really made much of themselves. They feel they have to attribute the success to themselves in a form of self justification when perhaps they should attribute some of that success to their family or previous mentors.[/rant]
