It's not always easy to follow this advice, but someone shared these with me years ago, and quite often some have taken root in me and got me over some verbal hurdles...

When we allow someone to ANGER us, that person CONTROLS us...

When someone says something that angers us... we are placing a higher value on that person's opinion than our own.

Gary is right: we should learn to let some things just roll off our back.

Quite often if we IGNORE unkind words or comments then we have victory over them and we don't allow them to pull us down.
