Chances are you don't get to be a (self-made) billionaire without throwing away $5k here and there.
If you're spending your time saving easily recoverable $5ks, you might get to be a millionnaire but you will never get to be a billionaire: it's totally irrelevant on that scale.
Equivalent statement:
You don't get to buy a house without picking pound coins up off the street.
Or you inherited it? Or your a middle eastern minor prince, or your a Russian who was in the first place at the right time and got a good deal ( ;-) ) on some Soviet privitaisation.
Not all billionaires pulled themselves up by their bootstraps
