People who make no mistakes are usually so cautious they lack the spirit of adventure. It's the perseverance of the dreamers that are willing to try and fail many times in the hopes of reaching their visions that are the real innovators of our society. Still, not making mistakes is an A+ in any teacher's book. So let's all try to be perfect and fastidious like them, rather than those pain in the neck risktakers out there always messing up the curve with their so-called "lofty endeavors". Sheesh.
