Look at this dumb turtle chasing after a dog like he's got a real shot at catching up; he'll never catch up. And yet even so, onward he plods, ne'er to abandon his reptilian hope—to be sure, he's a real idiot, but one deserving of some respect.
For the true experience lies in the chase, does it not? Without it, one grows indolent. Teeth once sharp grow dull. Eventually all rapids empty into still pools. Don't ever stop running turtle!! Your lot in this life is not to catch the dog, but with this attitude, young man, you'll never truly be far behind.
