Dr. Seuss once said, "Don't cry because it's over. Smile because it happened." Confucius declared that "It does not matter how slowly you go as long as you do not stop," and Thomas Edison asserted, "The most certain way to succeed is always to try just one more time."
Someone who needs encouragement can be helped simply by being reminded of the simple pleasures in life and that one should never give up. For example, consider the common phrase, "When the going gets tough, the tough get going." It can also be helpful to remind people that their friends and family are always there for them.
