Before 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.

William Arthur Ward

A teacher...

“The mediocre teacher TELLS. The good teacher EXPLAINS. The superior teacher DEMONSTRATES. The great teacher INSPIRES.” William Arthur Ward
