How can i fill my summer holidays?

So I'm 16 and having finished all my exams I am now on summer holiday. But i am so bored! so far my day consists of getting up at around 11 having crisps for breakfast then watching day time t.v for the rest of the day. I dont really have many close friends and I'm quite shy so thats why i'm not meeting up with anyone. I'm reading the complete works of jane austen at the moment, and only have mansfield park to finish, but to be honest theres only so much reading i can do in one day. what can i do to fill my summer? thanks :)
