I can never do tedious work quickly. As soon as I notice work that should be automated, I start cursing at the developer of the tool I am using for not offering an easy interface for me to plug into and just automate it, instead of having to rewrite the whole thing from scratch if I want to have it automated (and that's usually too time consuming, so I don't do it). So I'd be constantly unhappy doing it, which is a recipe for avoiding it, ergo being slow at it. That's why I am a huge fan of free software (and I've spent years on it too).
