"Hey, can somebody get me a metaphor?"

This illustration is obviously replete with symbolism and is a deep metaphor for something. I'm just trying to come up with something relevant to merit it being here, cause I like it so darn much. Let's see... I was inspired by my hero Lance Armstrong on his finish today in the Boston Marathon, just putting one foot in front of the other. Just doin' it! Livin' strong! (zzzzz.) Or maybe he's on the road to Pennsylvania for tomorrow's primary. Just remember, vote for Barry Obama, and vote often! Or... Q: How do you eat an elephant? A: One bite at a time! Q: How do you get through life? A: One day at a time! Q: How do you get where you need to go? A: Look at a map (Ooooh, another metaphor!) and start taking steps. And be sure to smile as you go! Whatever. Hope you enjoy my drawing.
