People need to feel cared for and appreciated, especially the people we love the most in this world, our friends and family members. Life is short. I started a gratitude blog because I think gratitude begets more gratitude, and the expression of gratitude begets...you guessed it...the expression of even more gratitude (always a good thing).
Don't save up your expressions of appreciation for a "rainy day." Don't be "stingy" with your love. Shout it from the rooftops! There is an abundant, never-ending supply of love, so there is no need to hold back.
