Compliment people. Magnify their strengths, not their weaknesses.
Be quick to praise people. People like to praise those who praise them.
It is never appropriate to comment on a woman's breasts. I would never do it on the street or at a supermarket, but when I'm sitting a table signing books, sometimes I notice that a woman will have remarkable breasts. And I will maybe quietly say something about it. It's not in a sexual way, because I'm a gay man - I would never say to a man "great ass" because that would be sort of creepy.. I hope it's not creepy to quietly tell a woman she has nice breasts.
Many people know how to criticize, but few know how to praise.
Don't praise your own good shots. Leave that function to your partner who, if a good sport, will not be slow in performing it.
I just think it's silly to be stingy with compliments. If you see someone and they strike you as beautiful in any way, why not let them know?
I'm definitely not one of those guys that's chirping the guys that dress super nice, because you know, there's guys out there in the league - and on my team in fact - that have great style. And I'm just like, 'go for it, man, you look good!'
You must not pay a person a compliment, and then straightway follow it with a criticism.
The art of conversation consists far less in displaying much wit oneself than in helping others to be witty: the man who leaves your company pleased with himself and his own wit is very well pleased with you.
