I would go to your doctor and get a physical, make sure you didn't have thyroid or other medical problems.

It is interesting that you talk about motivation for doing dull chores, etc. Who wants to clean up? Or, as my therapist once commented, "No one wants to clean bathrooms!"

What do you want to do and do you do it? It sounds like you are expecting your environment to come up with what you "should" do and then you want motivation to do that, which hasn't come from inside you.

Here's a good section on Motivation from Psychology Today: http://www.psychologytoday.com/basics/motivation

I think one has to decide what one wants (what one's goals are) and then just work toward that, it's not necessarily enjoyable or easy. Motivation does not come from outside us (nor does "inspiration"), it's not something magic. One has to practice being motivated, has to use the motivation muscle to get better at it.
