We all have possibilities we don't know about. We can do things we don't even dream we can do.

Make the other person feel important - and do it sincerely.

The unvarnished truth is that almost all the people you meet feel themselves superior to you in some way, and a sure way to their hearts is to let them realize in some subtle way that you recognize their importance, and recognize it sincerely.

Talk in terms of the other person's interests.

If some people are so hungry for a feeling of importance that they actually go insane to get it, imagine what miracle you and I can achieve by giving people honest appreciation this side of insanity.

If we are so contemptibly selfish that we can’t radiate a little happiness and pass on a bit of honest appreciation without trying to screw something out of the other person in return—if our souls are no bigger than sour crab apples, we shall meet with the failure we so richly deserve.

This is a hurried age we're living in. If you've got anything to say, say it quickly, get to the point and stop, and give the other man a chance to talk.
