There is an acute difference between laziness and wanting to increase efficiency. Laziness is not wanting to do anything at all, and can be not only detrimental, but actually leads to doing more work in the end because you either A) fucked it up the first time or B) didn’t get it done in the time given and have to cram at the end....neither of those is terribly efficient. However, wanting to do things more efficiently is a positive trait. This is what leads to many new ideas inventions and so on. This is what all (I think you’re right by saying all animals have this characteristic, I couldn’t think of any reason why an animal would do anything the hard way) animals have, not as much as laziness....whereas a human’s laziness can be caused by both sloth and a misguided thought of a better way of doing things.

Blah, time for work.
