Again, routine is the enemy of intelligence. Going through the same morning ritual, working at the same place, doing the same type of work, interacting with the same people, eating the same foods, watching the same TV shows, and otherwise subscribing to the same predictable patterns will in fact make you less intelligent. Routine is important for providing stability and security, but it should only provide the outer shell for tackling novel challenges each day. Push yourself to take in new input, the likes of which you’ve never previously experienced, and you will become smarter. Ideally you’ll want to tackle something new and non-routine at least once a day. Read a new book, listen to a new song, walk around a new location, meet a new person, eat at a new restaurant, play a new game, install new software – do something that provides fresh, new input to your mind.
