Plan to go to a free museum, or if you have some disposable money, maybe a zoo, or an aquarium, or a sporting event! Even if it's just the local softball game. Give yourself some new and different input.
I can't in the house (the dog gets v upset if I'm not in My Seat), but we have a spot outside we go sit at. There's a bench and I sit and read, while she runs around and rolls in the grass. Is v soothing.
