I like this brief and highly insightful advice, by Dr. Seuss, about anything that happens in life: 'Don't cry because it's over, smile because it happened.' Things change. Seasons change. Fashions change. People change. Everything passes. Familiar doors close and new doors open. Opportunity knocks, and circle of life goes on. Life moves on. Thus the beauty and the essence of Life can be summarized, IMHO, in just two words 'Life continues!' So, don't worry, be happy, and be in sync with ebbs and flows of life. Make it a good one!
