What do I do with my life?

So lately I've been having this terrible feeling that I don't do anything and I never have anything to look forward to. I'm not depressed as I am genuinely a happy person who likes talking to people and making dumb jokes with my friends, but I also seem to always have this thought that I don't do enough. I mean I sleep until noon everyday, I stay in the house all day on my computer either doing school work (which i have to admit takes a maximum of 2 hours a day not including weekends) or playing video games. I do that until I go to bed and then I stay up way too late and do the same thing day after day. There's no variety. All of my family members work so no one has time to take me out somewhere and when I do go out its just to like the store up the street or somewhere near by to eat. I'm never out for more than like 2 hours. My life is really boring and I don't like how it makes me feel. But for some reason I have no idea how to fix this. I want my life to be more fun and exciting again but I don't know how to get that back.
