Breakfast with Solomon - Proverbs 15:28
"The heart of the righteous ponders how to answer, but the mouth of the wicked pours out evil things"
How much time do you spend figuring out how you are going to say things? The wise person spends a lot of time keeping the words at the gate of his mouth before letting them out. For once they are said, they cannot be taken back.
One of the questions that is crucial to ask yourself is: What is an everybody-wins way of saying the things that need to be said. There is always a way; just find it. This doesn't mean that hard things don't need to be said, but there are better ways of speaking them than others. There are ways of allowing a person to retain their dignity or discover the information themselves.
