The value of a smile... It costs nothing, but creates much. It enriches those who receive, without impoverishing those who give. It happens in a flash and the memory of it sometimes lasts forever. None are so rich they can get along without it, and none so poor but are richer for its benefits. It creates happiness in the home, fosters good will in a business, and is the countersign of friends.
Dale CarnegieBitter criticism caused the sensitive Thomas Hardy, one of the finest novelists ever to enrich English literature, to give up forever the writing of fiction. Criticism drove Thomas Chatterton, the English poet, to suicide. . . . Any fool can criticize, condemn and complain - and most fools do. But it takes character and self-control to be understanding and forgiving.
