I like to mix up what I read in several ways.
1. I mix up genre. I tend to read a crime book or two, then must move on to, say, fantasy for a book or two, before moving on again.
2. I mix up how I read. I have a "glut" of reading on the Kindle followed by a "glut" of reading printed books, then magazines etc. (The one thing I've not really "got" on the Kindle are e-magazines but I suspect I'll get around to them eventually).
3. I mix up reading novels, short stories, flash fiction, non-fiction. So for a while I will only read novels, then move on to short story collections for a while, then have a non-fiction feast etc.
4. I switch between books and magazines. I do love a good magazine.
All of this means I'm never short of something to read!
I think mixing things up is good for my old brain and I like to ensure I don't neglect any type of reading material I like. It would be too easy to "just" read books or magazines and neglect the other.
What would I wish for though?
More time to read, definitely.
