But performance has less to do with butt-busting than with choices in what to learn/how to spend your time, don't you think? E.g., I could be working long hours manually moving data around, but if you come in and script that, you're already the higher performer. It's about where you've chosen to direct your effort vs. where I've chosen to direct mine.
