Hear, hear. I know a lot of people (me included) that learn better through failure than success. It's not until a pre-med student sees a dead person carved open that she really understands anatomy, and it's not until us HPC folks see a network of computers performing poorly or failing unexpectedly that we really understand all the dependencies between the parts. Our job as seasoned veterans should be finding ways for beginners to fail cheaply (both in terms of initial impact and recovery), so that the failure can be a good learning experience.
