Some really good stuff there.
Another one that Mark Cuban wrote was to cut your personal overhead as much as possible the less you have to pay out each month to survive the more likely you are to take the risk to do something. He started his first business when he was sharing an apartment with four other guys. He had hardly any monthly expenses so he had nothing to lose. If you have a house, two cars and a ton of bills each month you might allow yourself to not take that chance for the sake of being "responsible."
So look hard at your life and cut everything you don't need. Of course when you make it, you can get it all back
