Like dogs in a wheel, birds in a cage, or squirrels in a chain, ambitious men still climb and climb, with great labor, and incessant anxiety, but never reach the top.
-- Robert Burton
He who knows he has enough is rich.
There is a serious defect in the thinking of someone who wants -- more than anything else -- to become rich. As long as they don't have the money, it'll seem like a worthwhile goal. Once they do, they'll understand how important other things are -- and have always been.
