I'd like to say that I need more laziness, since that would imply that I'm hard-working and efficient. This is not the case. I'm plenty lazy, and if there's an existing solution to my problem then I'm using that.

Non sequitur. You appear to be confusing sloth and laziness. Hard-working efficiency complements laziness, as it implies getting the necessary work done with minimal effort and time. "Sloth" is simply slacking off or avoiding necessary work.
