Rabbi Aryeh Kaplan:
A method of breaking the gossip habit would be to take the Biblical verse:
"DO NOT GO AS A TALEBEARER AMONG YOUR PEOPLE
[Leviticus, chapter 19, verse 16]
and repeat it every day for a 20 to 30 minute period, like a mantra.
As one works on it, the message is gradually absorbed, and the self-control necessary to avoid gossip is attained.
