Have you ever tried running in deep waters? It's arduous. It's toilsome because not only does the viscosity provide far more resistance than air, the harder you push in one direction sends water pushing against you all the more forcefully on the return leg sweep. It's not just a battle of your legs, it doesn't stop there. You also feel this resistance on your arms and shoulders as you work. So you shut your eyes tight and you push, and push, you push yourself so hard till there's just nothing left. Then you lift your head up, open your eyes, and realize that, regardless of the endeavor, you're not making enough progress. But sometimes, by what seems like a miracle, you make it near land and then you trip, get caught in the undertow and it washes you further and further away from shore. It's fatiguing. There are moments when I feel life can be like that, except there is no end in sight; just you, the immensity of the sea and its intense resistance. It is strange that despite the fear that at some point in that wild struggle, I may keel over, drown and disappear.. I love the challenge.
