name that novel

"Mankind was my business. The common welfare was my business; charity, mercy, forbearance, and benevolence, were, all, my business. The dealings of my trade were but a drop of water in the comprehensive ocean of my business!"

tonight i went to des moines to take some stuff to my sister. i went out to eat with her and my brother-in-law at on the border. yummy. while i was driving to des moines the radio people were talking about the fda or someone or other cracking down on diet pills and saying that they won't solve your problem you need to diet and exercise and the one lady was saying not to buy a certain kind in particular because the one time she took one it gave her serious anxiety for the time being. then they go to a commercial and what are they trying to get you to buy? diet pills. it made me laugh...and then feel really bad.
