The Depths of Gratefulness

Over a beer a few days ago, a friend mentioned to me what his dad told him about gratefulness and it struck me hard. Some may say gratefulness is the act of appreciation, but true gratefulness is "giving your all with all that you can". Wow. I guess it's being able to dig deep into the depths of your given situation and not allowing anything to be taken for granted. Beyond the Thank You, gratefulness is making sure you've done your part to your fullest potential with a sense of social responsibility. What are you grateful for and how have you demonstrated it?
