It is a mistake to confound strangeness with mystery. The most commonplace crime is often the most mysterious because it presents no new or special features from which deductions may be drawn. This murder would have been infinitely more difficult to unravel had the body of the victim been simply found lying in the roadway without any of those outré and sensational accompaniments which have rendered it remarkable. These strange details, far from making the case more difficult, have really had the effect of making it less so.
Civil society people - these are the people - civil society groups are the people who need to monitor the aid to ensure that the aid is directed to what it is supposed to. And in order for them to do so, they need to have the space, they need to have the freedom, and they need to have the right to demonstrate, and to petition their government. They can't do that in Ethiopia; they can't do that in Eritrea; and so this is why I was cautioning that we may be repeating some of our old mistakes.
Experience is a wonderful thing. It enables you to recognize a mistake when you make it again. If all economists were laid end to end they would not reach a conclusion.
It is not a mistake to commit a mistake, for no one commits a mistake knowing it to be one. But it is a mistake not to correct the mistake after knowing it to be one. If you are afraid of committing a mistake, you are afraid of doing anything at all. You will correct your mistakes whenever you find them.
The degree of sympathy we feel regarding another's fiasco is directly proportional to how easy or difficult it is for us to imagine ourselves, under like circumstances, making a similar mistake.
I consider that a man's brain originally is like a little empty attic, and you have to stock it with such furniture as you choose. [...] It is a mistake to think that that little room has elastic walls and can distend to any extent. [...] It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.
When you have success on the field, you're more popular and you have that fame that comes with it. You realize you're in the public eye more and you've got to be a little bit more careful about some of the things you're doing out in public and make sure you're smart about the things you say. You're still going to make mistakes from time to time, but you represent an even greater population and people are that much more looking for you to be in the wrong place at the wrong time or fall down or say something really stupid that's going to get you in trouble.
