How can you restrain yourself from backbiting?

yup we are all guilty of doing it. including myself. sometimes i do that and talk about another person behind their back and not even notice OR i catch myself in mid sentence. if i catch myself i usually stop and directly tell the people im talking to that we shouldn't be talking about so and so. in an effort to kinda reverse what i said, i make myself say at least ONE good compliment about that person and just leave it at that. i try my best not to talk about anybody and if i do feel the need or whatever then i always balance and say good things about them as well. i mean just try to find any good qualities about the person. no matter how much you don't like them, no matter if you are in the right and they are in the wrong, if you talk badly about someone and you catch yourself doing it, stop and balance it out by saying something positive about them and just leave it at that. you don't want to get bad deeds for slandering. so might as well bite your talk, say one good quality about that person to get good deeds and just move on and leave it at that. i hope this makes sense and helps a bit. take care.
