We believe that what we possess we don't ultimately own. God is merely entrusting it to us. And one of the conditions of that trust is that we share what we have with those who have less. So, if you don't give to people in need, you can hardly call yourself a Jew. Even the most unbelieving Jew knows that.
Jonathan SacksThe wisest rule in investment is: when others are selling, buy. When others are buying, sell. Usually, of course, we do the opposite. When everyone else is buying, we assume they know something we don't, so we buy. Then people start selling, panic sets in, and we sell too.
