Be an optimiser

You know those people when you ask them for a recommendation they kind of um and ah and don't really say much- neither one way or the other? You ask for a good restaurant and they say they know an OK one. You ask for a decent plumber and they say this guy was OKish. In a sense they are protecting themselves against being blamed if something goes wrong; but they are also not optimising. If you have only OK restaurants to go to you're not looking hard enough, you're not optimising your life. Which also means you are less use to other people. If you can't recommend things then you are giving up something you don't need to give up.
