Don't forget to shock your mind. Read a book from an author you never thought you'd like. Read a different newspaper online (or in your brain-housing-capacinator or whatever news medium you'll have when you're older). Go somewhere new and do something different. Say something to someone you've never said before.
It might hurt at first.
You might get tired.
Soon you'll start thinking differently.
Then you'll have new ideas.
And you'll start to get excited.
If you go back to your usual activities, you'll see them through a whole new lens. This is good. You'll be learning.
