Getting High On Life!

What makes you enjoy the day?  What does it mean to be human?  What differentiates us from other life forms?  Do you pay attention to all your possiibilities and capabilities?  What really matters to you that you would go after no matter what adversity came your way?  Why would you keep going when others would quit?  What takes your level of existence to the next highest level?  Do other people motivate you or do you find satisfaction on your own?
