If a man’s heart is rankling with discord and ill feeling toward you, you can’t win him to your way of thinking with all the logic in Christendom. Sc… - Dale Carnegie

And the pathetic part of it is that frequently those who have the least justification for a feeling of achievement bolster up their egos by a show of tumult and conceit which is truly nauseating. As Shakespeare put it: “ … man, proud man, / Drest in a little brief authority, / … Plays such fantastic tricks before high heaven / As make the angels weep.

That is the way Emerson said it. But here is the way a poet -the late Douglas Mallochsaid
it:
If you can't be a pine on the top of the hill.
Be a scrub in the valley-but be
The best little scrub by the side of the rill;
Be a bush, if you can't be a tree.
If you can't be a bush, be a bit of the grass.
If you can't be a muskie, then just be a bass-
But the liveliest bass in the lake!
We can't all be captains, we've got to be crew.
There's something for all of us here.
There's big work to do and there's lesser to do
And the task we must do is the near.
If you can't be a highway, then just be a trail,
If you can't be the sun, be a star;
It isn't by the size that you win or you fail-

Be the best of whatever you are!

Welcome the disagreement. Remember the slogan, ‘When two partners always agree, one of them is not necessary.’ If there is some point you haven’t thought about, be thankful if it is brought to your attention. Perhaps this disagreement is your opportunity to be corrected before you make a serious mistake. Distrust your first instinctive impression. Our first natural reaction in a disagreeable situation is to be defensive. Be careful. Keep calm and watch out for your first reaction. It may be you at your worst, not your best. Control your temper. Remember, you can measure the size of a person by what makes him or her angry. Listen first. Give your opponents a chance to talk. Let them finish. Do not resist, defend or debate. This only raises barriers. Try to build bridges of understanding. Don’t build higher barriers of misunderstanding. Look for areas of agreement. When you have heard your opponents out, dwell first on the points and areas on which you agree. Be honest. Look for areas where you can admit error and say so. Apologize for your mistakes. It will help disarm your opponents and reduce defensiveness. Promise to think over your opponents’ ideas and study them carefully. And mean it. Your opponents may be right. It is a lot easier at this stage to agree to think about their points than to move rapidly ahead and find yourself in a position where your opponents can say: ‘We tried to tell you, but you wouldn’t listen.’ Thank your opponents sincerely for their interest. Anyone who takes the time to disagree with you is interested in the same things you are. Think of them as people who really want to help you, and you may turn your opponents into friends. Postpone action to give both sides time to think through the problem. Suggest that a new meeting be held later that day or the next day, when all the facts may be brought to bear. In preparation for this meeting, ask yourself some hard questions:
