It does not sound like you want to do other stuff. That's not either depression or being lazy. There are lot of things that would be "good" for us but unless we truly want them in our lives, they ain't happening and that's okay! Do some exploring of what makes you happy instead of just picking things off lists or because you know they make you feel better but are more work than the benefit?

When I was in college, I had a particular Saturday routine that involved walking down to the town (about half a mile, maybe more) and/or to the Student Union and getting particular magazines and candy I liked and then I'd relax on my bed and enjoy myself. However, I often skipped classes that were much closer :-)

We do, buy, experience what we want to do! Figure out how to "want" what you think would be good for you or figure out how to make what you know you do want good for you.

I just started yoga, I'm taking a "class" two or three times a week and lucked out; I already knew/liked the teacher and am not getting a lot of grief from myself about going. However, I did not go when I first knew of the class, I had to get over my initial negatives. So, you might decide to do yoga for a week and then re-evaluate, for example? Give yourself a smaller time period and permission to "try" things and give them up if after X period you decide they're not for you at this time? I'm doing yoga through July. The teacher is then joining forces with a friend and they'll move the studio so I might or might not like that. But right now I'm just concentrating on July and that's very doable/enjoyable for me.
