I agree. Most people, when they got hit in their endeavors, give up. If not the first time, after a few times, almost certainly. It takes a certain type of resilience and determination to keep trying, and pick yourself off the floor. Another way it's been said is: it's a marathon, not a sprint. And during a marathon (although I haven't run in any, not even close, but I read about it) you can experience various sensations and have to overcome possible multiple turning points that could have made the difference between continuing the race and abandoning it.
