The civil law regards the spendthrift as akin to the lunatic, and frequently takes from him the management of his own affairs.
The next rule is to pay ready money, and never, on any account, to run into debt.

The person who runs into debt is apt to get cheated; and if he runs into debt to any extent, he will himself be apt to get dishonest.

"Who pays what he owes, enriches himself." The next is, never to anticipate uncertain profits by expending them before they are secured.

The profits may never come, and in that case you will have taken upon yourself a load of debt which you may never get rid of.

It will sit upon your shoulders like the old man in Sinbad.
Another method of economy is, to keep a regular account of all that you earn, and of all that you expend.
