I think there's a slight difficulty with that though, because a 'lack of motivation' is often associated with depression. So, with depression, being ill can cause a lack of motivation if there is a reduced 'desire' or 'interest' to engage in activities. But I agree that we need to change the parameters when talking about 'motivation' for people with chronic or severe disabilities or illnesses. Although I rarely feel excessively up-beat and full of vitality (and never feel like partying or bungy-jumping), there are plenty of low-key interests in my life. which I enjoy engaging in. So perhaps our 'motivation' is displaced to a focus on new, non-usual, activities. As Hip says, he has plenty of motivation for new activities that he wasn't involved in previously, so his motivation has been displaced from tidying/organising to researching health issues. I think my levels of motivation fluctuate, depending on the severity of my symptoms. It's not surprising, considering the nature and severity of the symptoms. For example, sometimes when my symptoms are at their worst, I'm very grateful for my sofa, and I don't feel like doing anything other than resting, and perhaps watching a film. But that doesn't mean that I lose interest in everything. It's not the same as losing interest in life in general, as can happen with depression. I'm still interested in things, unless I'm totally knocked out, temporarily. When my symptoms are less severe, then my mental vitality and enthusiasm for life do increase somewhat. When someone has flu, they don't have much motivation, but are bed-bound, and are often content to be bed-bound, preferring to stay in bed rather than do activities. This is because of the severity and nature of the symptoms. So physical illness can lead to reduced motivation. Anyway, it's a very complex issue, and an interesting discussion.
