Show appreciation

Let others feel that you like them.

For instance, compliment the new hairstyle of your wife, notice how the coat of your secretary suits her personality, praise a job well done by your kids, and so on.

Watch a smile and pleasant response come from the person being complimented.

However, do it sincerely.

There is this thing known as dishonest flattery that can ruin a relationship.

Some people can recognize if you are being truthful or not; they can see right through you.
