The only good thing about being lazy.
Let me just start off by saying if you're a generally lazy person, chances are you're in a situation where you're quite unmotivated. So first find something you're passionate about.
That said, nobody likes a lazy person. Especially a lazy person who's working for them.
Working with a lazy person is like pulling a giant wooden log up a hill. It is frustrating and exhausting.
But ever once is a while you find a lazy person who actually inspires innovation, all because they're too lazy to do things the current way. Laziness tends to encourage one to find a more efficient way to do things.
For instance, I had a co-worker at my software job (Day job I hope to quit) who was intensely lazy. But this guy was responsible for some of the best automation tools our department has ever worked with. All this was as a result of the fact that he didn't like the grind of doing things the old way. Actually, as a result, he was given a new position where he was allowed to work on new tools for the company. I also think there was an uptick in his motivation as a result. :-)
