Confine yourself in a space. We tend to behave and act according to the walls around us. The easy way is to stay within the room, acknowledge its walls and accept being limited to its floor.
Instead, start exploring the boundaries. Walk the walls or simply tear them down. Flip the whole room upside down or collapse it all together. Question and explore the concept of a room. It might not take you anywhere new but it could make a big difference on how you enjoy the journey or appreciate the space you are in. Unconfined.
