I just moved into my own apartment and need fun ideas! Help please.

So I'm 21, have a one bedroom apt. Been living here for about 3 weeks so far.

I feel like there's not much to do here so things that will make it a little more fun.

So does anyone have any neat ideas or tips?

Edit: If you can, could you please upvote this? I know thats horrible to say but I want alot of people to see this post so that I can get more ideas or tips from poeple who may not have seen this post otherwise. I really don't care about the karma. I just want a fun apartment that is my own and interesting.
