Eat a third and drink a third and leave the remaining third of your stomach empty. Then, when you get angry, there will be sufficient room for your rage.
Babylonian Talmud
Do not consider it proof just because it is written in books, for a liar who will deceive with his tongue will not hesitate to do the same with his pen.
Moses Ben Maimon Maimonides
Say not, when I have leisure I will study; you may not have leisure.
