From the historians' point of view these assumptions must be realistic or they are junk. If we use the assumption of perfect foresight by businessmen to construct data, the question of its empirical validity is crucial. Altering the assumptions, whether about the model or about the data, can make a substantial difference to both the data and the answers.

It's about getting the kids up and fed, getting one to school, getting the other down for a nap, going to the grocery store, picking one up from school, getting the other one down for another nap, cooking dinner... I live my life at these two extremes. I'm either a full-time stay-at-home mom or a full-time actress.

I didn't see it then, but it turned out that getting fired from Apple was the best thing that could have ever happened to me. The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything. It freed me to enter one of the most creative periods of my life.

All that stuff about heavy metal and hard rock, I don't subscribe to any of that. It's all just music. I mean, the heavy metal from the Seventies sounds nothing like the stuff from the Eighties, and that sounds nothing like the stuff from the Nineties. Who's to say what is and isn't a certain type of music?

Let us pass to the despotic part of the soul, spirit. We must not eliminate it utterly from the youth nor yet allow him to use it all the time. Let us train boys from earliest childhood to be patient when they suffer wrongs themselves, but, if they see another being wronged, to sally forth courageously and aid the sufferer in fitting measure.
John Chrysostom
For Christians above all men are forbidden to correct the stumblings of sinners by force...it is necessary to make a man better not by force but by persuasion. We neither have authority granted us by law to restrain sinners, nor, if it were, should we know how to use it, since God gives the crown to those who are kept from evil, not by force, but by choice.
John Chrysostom
