That’s why, in my 40’s, I am pushing myself harder than ever.
A few things might not be working as optimally as they have in the past, but I recognize the finite resource and as such am using my physical endurance while I have it.
Much of endurance today is actually tricking myself into thinking that what I am feeling is not pain. Remember back when you were young, and questioned whether something was pain or just a funny feeling. I just ask myself one thing: if I continue will it get worse or better? Often times it’s better or unknown, in which case the answer is forge-on, what pain? That’s not pain, it’s experience. Push through. Anything worth doing is not easy. Perceived value is lavished upon only those that make it over the finish line. And many other things I tell myself whilst running actual marathons.
