I noticed that I got better if I took a 20 minute nap at around 2pm. But usually at that time I'm not sleepy enough to take one. I feel sleepy enough at around 5 or 6pm, but then I sleep for 2 hours, and still wake up really tired.
In this last week though I realised that I can get more energy even if I take a nap at 5pm. It just has to be 20 minutes though, and not more. I find it really hard to force myself back up (I just feel like sleeping more), but after a few minutes it feels much better.
About the hoop, I thought about it before and I was thinking of getting one but it has to be the full set (not just the backboard) because I don't have any place to put a backboard on. The full set is too expensive and I have nowhere to store it.
I think right now the only thing I really want to do is play basketball. I can't find any place nearby where I can play though, the closest place takes me 40 minutes to get there (and I'm not even sure I can still play there).
Apart from that I would like to do something that gets me out of my desk but that isn't very tiresome (like basketball), but I don't really know what sort of thing I could do. I want to learn japanese (already learned some of the basics) but I always feel braindead in the afternoon.
