I think the best thing to feed my brain is reading. It’s something I don’t do anywhere near enough of, but I can feel myself getting smarter (or at least, some of my smarts returning after magically disappearing once high school let out). It’s something I did religiously as a kid. I always had stacks of books waiting for me from the library, and I’d devoure story after story. I remember I started with Grug as I was just beginning to read, then moved to Goosebumps and the Baby Sitters Club. When I was a bit older I got into the Mary-Kate and Ashley books, then John Marsden’s the Tomorrow Series. Then someone introduced me to the Sims and suddenly reading wasn’t so important any more.
I got back into it a couple of years ago, re-reading the Artemis Fowl books (which are awesome!), then getting lost in the back catalogues of Catherine Ryan Hyde and Jodi Picoult. I finally got into Harry Potter as well. So many wonderful stories and characters! As much as I love video games and cartoons, nothing makes my brain tick like a good book. I really do need to make more of an effort to keep reading. It’s so easy these days to chuck on the TV instead.
