From Vedder at Minding the Campus.
Math and science are difficult, and they aren't all about "what I think" and "what I feel." Failure is a good thing in a meritocratic field because it separates those with potential from those without. Whether it's banks or students, America needs more room for healthy failure.
Failure is more important than success, because more can be learned from it. In the end, success in achieving goals is better, though. Much more enjoyable.
