Be thankful for this day, and you will fill it with joy. Be appreciative of those around you, and they will bring much value to your life. Be grateful for your opportunities, and you'll find yourself making the most of them.
Be thankful for what you have, and you'll get more from it. Be grateful for the challenges, and they will help you become stronger. Appreciate the dark, cloudy days and they'll instantly become brighter. Appreciate the sunny days, and you'll enjoy them even more.
Those things you take for granted will fade from usefulness as you forget they're even there. By contrast, those things for which you're thankful remain readily available and will grow even stronger as a result of your appreciative attention.
Consider how very fortunate you are. Consider it often. The more you count your blessings, the more there will be to count.
