The origin of many personal conflicts comes from the inability to distinguish between opinion and objective fact.
If it is only your opinion, then ask God for the grace and humility to hear and understand the opinions of others. Maybe they have something of value you need to hear. If it is only your opinion don’t value your own worth so much that you are willing to cause relational damage just to make your point.
A fool finds no pleasure in understanding,
but delights in airing his own opinion. (Proverbs 18:2)
If what you are presenting is factual then ask God for the patience to present what you think with a quiet and gentle spirit. Pleasant words promote instruction, not your angry, decisive tone. Consider others more important than yourself.
Love and honor those close to you so that they will want to hear what you have to say, even if they disagree with you.
It is always the path of wisdom to know when to say nothing and take your concern to God and his word instead of trying to force someone to bow to your pride.
