I know this sound lame, but I like studying, I can spend hours after school learning about school and non school topics. It's kinda sad. I also love reading but after reading a lot of fiction I became kinda tired and started reading non-fiction about history, politics, biology, ... but that can be very exhausting, so I am not reading that much any more. Of course, I watch lots of dramas and movies but does that count as a hobby?
