For Hamlet, greatness means willingness to fight for reasons as thin as an eggshell: anyone would fight for things that matter; true heroes take their personal honor so seriously they will fight for things that don’t matter.

As you craft a plan to expand to adjacent markets, don't disrupt: Avoid competition as much as possible.

If you invest in Microsoft or Oracle, or a number of other companies for that matter, you're fundamentally making a bet that there's going to be no innovation. So an investment in Microsoft is a bet that the operating system is going to stay the same, it won't be replaced by Linux, Google Docs, or a mobile platform like iOS or Android.

When you are starting a new business you don't want to go after giant markets. You want to go after small markets and take over those markets quickly.

All happy companies are different: each one earns a monopoly by solving a unique problem. All failed companies are the same: they failed to escape competition.

Anti-aging is an extremely under-explored field.

The value of failure is greatly over-rated. It's a preposterous myth.
