These are some characteristics of laziness according to a book I just read. Some of them seem the same as what one encounters with depression. In either case one can work to get over them by observing one's thoughts. Just observe and don't make judgments. Then see what happens. This observing of one's thoughts is a new strategy in treating depression. Usually depressives tend to think they are worthless for example. If you examine your thoughts and come across this thought you can refrain from calling yourself worthless. If you do it enough, the tendency to call yourself worthless will occur less often. Try it.
1. Tendency to avoid inconvenience. I don't exercise because I would have to change clothes and go to the gym. (A depressive would probably not exercise because he has no energy.)
2. Sense of hopelessness; poor me; Aren't up to dealing with the world.
Even though we try to get out, we have hopelessness inside. (This sounds to me very much like depression.)
3. Characterized by resentment: Giving the world the finger.
4. The world is messed up. It's not giving me what I want. (In my opinion this would best fit the definition of lazy. I don't know if depressives have this outlook so much. At least I don't. I usually blame myself, not the rest of the world. I am worthless, the rest of the world is okay. That's how I want to be.)
