Compliments are little gifts of love. They are not asked for or demanded. They tell a person they are worthy of notice. They are powerful gifts. But compliments work only if they are sincere reflections of what we think and if they are given freely and not coerced.

The art of the compliment is not only a powerful social skill; it is one of the most fundamental. You don’t need to be an expert to do it well. You just need to be genuine. Compliments are in fact one of the finest tools for acquiring more social skills, because the returns are great and immediate. They escalate the atmosphere of positivity and become social lubricants, fostering the flow of conversation and advancing communication by enhancing receptivity.
