The obvious one is procrastinating.
Honestly, I've never really had a hobby. I don't make things. I don't collect anything but dust. I don't bake unless I have to. I like to read, but it seems I never have the time. I used to write but that's when I didn't have to work and had a lot of leisure time (oh, how we only thought college was hard).
Dang. I started a blog to show off how wonderfully interesting I am, but this meme has blown my cover.
