It sounds from this like you aren't being challenged enough. For some people that is a good thing, as they like the idea of sitting around doing nothing 90% of the day. But it sounds like you want something more, and I expect you will not find it unless you are working in a much more challenging environment. Bluff yourself into a place where you have little idea what to do. Once you're scrambling around trying to keep your head above water, you'll lose your laziness. Or realize that's what you prefer.
