The most important thing to do if you find yourself in a hole is to stop digging.

don't do things that kill you.

Before you speak, listen.
Before you write, think.
Before you spend, earn.
Before you invest, investigate.
Before you criticize, wait.
Before you pray, forgive.
Before you quit, try.
Before you retire, save.
Before you die, give.
