No, that doesn't work. What is constant happiness bad for? It's not bad for happiness. You might mean that it's not moral, but I can't see the harm in it. Or you might be saying that it's not possible. That sounds more likely: it does seem that people constantly update their standards and expectations in order to maintain a state of discontentment (and, conversely, people will lower their horizons when necessary, in order to maintain a sense of progress).

But then, a satisfactory state of striving ever onward might be called happiness, if you like. Discontentment and all. I suppose happiness has contexts, and the main thing is to be happy in your autonomy, that is, not having your personal business disrupted by catastrophes and interference, in the widest context.
