I want to tack on cycling to this. I can't count the number of times I've wanted to solve all of the world's problems at the beginning of a bike ride. And the result is always the same. The primary problem that I end up solving is 'how the hell do I move myself over the next 60+ miles without blowing up and getting dropped by the pack.' And not falling - not falling is key. Dodging cars, cyclists, potholes, cracks, animals, gravel, basically anything that can ruin your ride, becomes a major focus. Then after you finish the ride, you are on a physical high from the exertion and a mental high from getting to take a break from your petty little problems. Man I want to go ride now...
