And that's what counts. Let's say a rabbit and a giraffe both have to get across the same river. Wouldn't it be a whole lot more challenging for the rabbit? The giraffe can practically walk across in its sleep. The rabbit needs to give it everything it's got, think and plan its strategy, use resources to help it along, and it's going to take longer to get the job done. When the giraffe was on the other side a long time ago, and the rabbit is still hopping from rock to rock, is that the rabbit's fault? Is the rabbit unsuccessful? Heck no. The rabbit's a doggone genius.
