Religion: Proverbs 11

When reading Proverbs 11, I noticed that some of the things written for the fool I have been doing. As a believer in Christ, we must listen to God's word and abide to it. I haven't been the best christian and I realize that, so I will change. In Proverbs 11:23 it says " A prudent man concealeth knowledge: but the heart of fools proclaimeth foolishness." I was looking at this verse and it reoccurred to me that I was doing the same thing as the fool. Saying all my plans in life to everyone, actually ruin them and make me look bad, but to hold my knowledge and hold my peace will I be prudent. Proverbs is a book for the rights and wrongs, the wise and foolish. We just have to keep guard and ask ourselves everytime we speak; would this be the wise mans' mouth? or the fools?
