I relate to this post because recently (last saturday) I was feeling exactly like you described, bored, I didn't want to do anything, I spent all morning in my bed watching soccer then at 2pm I realized that I was wasting precious time and got up and went jogging for one hour, after my work out the feeling was great and made me happier than being all day doing nothing at home, like you well put it, I just had to go out and do it.
