Everybody has luck both good and bad. Some people just have the faith and determination to make good on the good luck and not get drug down by the bad. Rush was fired many, many times. For a failure a dad like Rush had could be an excuse for the failure. He also had some pretty "good" luck being a radio talk show host and going deaf. Give me a break fella.
Success does not lead to good decisions. Good decisions lead to success. I think it is called free will in the Christian Bible.
If Rush's well-to-do father hadn't owned the radio station, Rush likely may never have cultivated an interest in radio to begin with. He had exposure and assistance people of lesser means don't have.
Lot's of people fail and never give up and yet they never attain even a fraction of the success Rush has enjoyed. Somewhere along the way one has to get a break, otherwise known as good fortune, and not everyone does. Those who do, don't often admit it.
But thank goodness God doesn't judge us by the size of our homes or bank accounts, and takes all things into account. Some very wealthy people, with big homes and good careers, are going to find they weren't all that successful after all. And some people of very modest means are going to learn all along, they really were the richest people in town.
