"You want to screw up. If you don't screw up when you start out, then you are overqualified for the position. Because if it was anything less than a big opportunity that affords you a ton of growth, then you would know how to do everything that's required. That it feels overwhelming - that you make loads of mistakes - lets you know that you took a big step, that you're learning things, that you're being challenged. Little failures are how you know you're succeeding."
