Words are powerful and can be used to either build up or tear down. Be very careful what you say to others. Once said, it can never be taken back. And the truth is people can forgive, but very seldom do they forget.
Negative talk you say to yourself is just as destructive as the negative talk you say to others. Most of us would never speak to others the way we speak to ourselves.
Watch your words when speaking to others and yourself. If you cannot say anything positive, then say nothing at all.
