Yesterday I sat outside my home as the sun rose, and as I listened to the day come alive around me, my pet turtle Otis trundled by.
I watched him make his way through the yard, not letting the bird bath or the large moss-covered rocks spaced (I hoped) artistically deter him from his goal. While I wasn't sure what his goal was - perhaps just to reach the other side of the yard - what I realized was that he was determined to get there, and those obstacles in his way were simply momentary blocks. He reached them, paused for a second, then chose a direction and walked around them.
This is the difference, really, between those who continually move forward and those who don't.
And while our obstacles as people are perhaps more imposing that a birdbath and a big rock, in the end it's a matter of choosing to either stop and be defeated by those things in our path, or pick a new tangent and find a way around them.
Ultimately, that's what gets us where we're going.
