What's in the definition? Everything

To truly understand what we're striving for, here are the definitions of our challenge:

• Consciousness: n. a state of being aware  
• Contentment: n. a state of happiness and satisfaction
• Gratefulness: n. acknowledgment of having received something good from another

So much meaning in those three words.  They sound so simple yet if I apply them to how I look at my possessions and needs vs wants, it puts so much perspective on things. 

Will this change me?  Can I open my eyes and live in a state of happiness--recognizing the good I have already been blessed with??  And, just as importantly, can I live with that view in such a way that it will be contagious to those around me???
