Maybe working on those motorskills would be something to take up? Maybe an art class or pottery or something along those lines?
That language is a good idea if you have ambition for it. I've thought about that myself. Apparently Duolingo is a great way to learn.
If you like exercise, maybe try doing something specific that you've never done? I was getting bored with just regular workouts and took boxing lessons for a year or so. I loved it.
Maybe an instrument if you've ever had that desire?
