One who guards his mouth and tongue [from speaking loshon hara] guards his soul from tribulations ~ Mishlei 21:23

If not speaking loshon hara is very difficult for you, start off by designating just an hour a day where you absolutely commit to not speak or hear loshon hara.   Over time, look to increase those hours and see where it takes you.  But realize that even if you can’t increase the time, that one hour will be very beneficial to your soul.  Start today!
