Second the idea that my programming output has declined in terms of quality as I focus more on business related aspects. It forces you to look at everything in context -- better code quality gets you more maintainability, but at what cost? Every decision I now make has a trade-off; as a programmer, I can afford to throw more time to elegantly solve a problem. As an entrepreneur, I just need it to work as well as I've defined, for a specific cost.
Great Baggins reference as well.
